This connected directly to his own game, Gone Fission!, which was inspired by Chain Reaction. - Why it matters: It’s a personal “full circle” moment showing how retro scenes and preservation fuel modern indie projects. - Key stakeholders: Retro gamers, Play Expo vendors (e.g., The Gaming Newsagent), Atari ST enthusiasts, indie devs. - Risks and tradeoffs: Nostalgia bias; scarcity of accurate preservation artifacts; hardware/software compatibility limits for archival play. - Bottom line: Serendipity at a retro event validated creative influences behind a current side project. ## 📖 Main Content - Core: The author describes Play Expo’s familiar layout and vibe, then a quiet-afternoon dig through The Gaming Newsagent’s boxes yields ST Format 70 featuring Chain Reaction—a grid-based, cascading “atom” strategy game for Atari ST with colorful graphics and sound, distributed as shareware with a £5 registration. - Context: - Atari ST: a late-80s/early-90s home computer platform popular in Europe. - Shareware: try-before-you-buy distribution relying on registrations for support. - ST Format: a leading UK magazine for Atari ST users in the 90s. - Uncertainties: Exact details of the author’s future article comparing PD/derivative versions; preservation links/image sources beyond brief mentions. ### 🗒️ Notes - “One of the highlights of my year is Play Expo – a weekend away in Blackpool that has a bunch of retro and modern video games.” - Trading hall tactic: visit mid-Saturday when crowds thin; easier browsing and chatting. - “One such place is The Gaming Newsagent… started as SegaMags, but branched out into all such other magazines.” - Find: “St Format issue 70, from May 1995. An immediate buy.” - Chain Reaction overview: - Up to six players; place atoms on grid cells (corner/edge/center thresholds). - Cells at critical mass explode, sending atoms to adjacent cells. - Captures flip opponent atoms; cascades cause board wipes. - Not hard-drive compatible; requires dearchiving to blank disk; 512K memory; Falcon incompatible; 152K uncompressed. - Shareware with “justifiable plea” to register for £5; “colourful graphics and neat little sound samples.” - Personal link: “Gone Fission! was inspired by Chain Reaction… weird kind of full circle on a side project that dominated this year.” ## 📚 References - A Full Circle Reaction (original post): https://www.rhyswynne.co.uk/a-full-circle-reaction/ - Play Expo (events site): https://www.playexpogaming.com/ - Atari ST (overview): https://en.wikipedia.org/wiki/Atari_ST - Shareware (definition/history): https://en.wikipedia.org/wiki/Shareware ## 🗣️ Paraphrase - Paragraph A: The author loves the dependable ritual of Play Expo—arcades up front, traders left, pinball right, consoles and stage at the back—and the familiar faces each year. - Paragraph B: A calmer Saturday afternoon browse at The Gaming Newsagent led to an instant purchase of ST Format 70 for its Chain Reaction feature. - Paragraph C: Chain Reaction is a shareware, multi-player atom-cascade strategy game on Atari ST; its mechanics create dramatic chain reactions and territory flips. - Paragraph D: The author’s Gone Fission! drew on Chain Reaction and other PD variants, making this discovery a neat “full circle” moment. ## 📰 Newsletter - Blackpool’s Play Expo delivered retro serendipity: Rhys Wynne unearthed ST Format 70 and revisited Chain Reaction—the cascading atom puzzler that helped spark his own Gone Fission!. Retro mags and shareware still shape today’s dev journeys. For WordPress folks: consider how archival content and small mechanics can inspire modern UX. Spotlight: reproducible design patterns, respectful attribution, and “shareware-era” funnels applied to open-source plugin onboarding. ## ✅ Action Items #### DevRel - Publish a short demo dissecting Chain Reaction mechanics with modern SDK examples. - Office hours on retro-to-modern game mechanic translation. - Create examples repo: grid-cascade logic in multiple languages. #### OSPO - Draft guidelines on attributing inspirations from legacy/shareware sources. - Add license review check for retro-derived assets. - Set SBOM policy for bundled game assets. #### Community - Host a “retro mechanics jam” with mentorship. - Create first-issue tickets: implement explosion/cascade logic tests. - Share transparent budgets for preservation partnerships. #### WordPress - Core: explore lightweight animation primitives useful for cascade effects. - Documentation: examples-first pattern for grid-based interactions. - Training: lesson plan on porting legacy UX to blocks. - Accessibility: audit motion/flash for prefers-reduced-motion users. - Meta: reproducible bug templates for interactive UIs. - Plugins: provenance checks for retro assets. #### The WPCC - Fund microgrants for preservation-driven plugin ideas. - Run governance clinics for archival collaborations. ### FAIR - Require provenance notes and signature checks for imported assets. - Standardize operator agreements and sunset clauses for funded experiments. ## 🧪 Hypotheses - Retro magazine artifacts measurably increase indie dev output within 3 months. - Grid-cascade mechanics raise session length vs. match-3 baselines. - Shareware-style “pay what you want” boosts community engagement for small plugins. - Event serendipity (in-person finds) correlates with new side-project starts. ### 📊 Methodology - Quasi-experiment: provide curated retro artifact packs to a dev cohort; measure commits/releases. - A/B test cascade vs. non-cascade puzzle modes; track retention/time-on-task. - Payment model experiment on a small plugin/theme; compare engagement metrics. - Survey attendees post-event; track initiated repos within 60 days. ### ❓ Questions - Which PD variants most influenced Gone Fission!’s final mechanics? - What preservation gaps block hands-on play today? - Can WordPress onboarding borrow “shareware nudges” without dark patterns? ### 🔮 Future Research - Catalog and emulate ST shareware titles with permissive redistributions. - Pattern library: classic mechanics mapped to modern web components. ### 💡 Implications - Practice: mine legacy mags for reusable UX patterns. - Policy: formalize attribution when inspirations are identifiable. - Education: teach reverse-engineering of retro mechanics. - Funding: support preservation that enables modern reuse. ### 🧠 Learning Styles Assessment - Reading level: Flesch–Kincaid Grade ≈ 8–9. #### 👀 Visual learners - Present: mental model of grid cascades. - Improve: simple cascade diagram, before/after captures. #### 🔊 Aural learners - Present: none. - Improve: 3-minute audio summary. #### 🗣️ Verbal learners - Present: clear definitions of shareware, ST Format. - Improve: analogies to modern indie distribution. #### 🧩 Kinesthetic learners - Present: none. - Improve: interactive sandbox for cascade logic. #### 🧠 Logical learners - Present: stepwise cell-threshold rules. - Improve: decision tree f - Summary: One of the highlights of my year is Play Expo – a weekend away in Blackpool that has a bunch of retro and modern video games.

It’s pretty much the same every year: arcade machines as you walk in, trading hall to the left, pinball machines to the right, home consoles towards the back along with the main stage. Play Expo has a familiarity to it, which makes it a must attend every year for me. If only to see the same faces every year. The traders hall is often a place I go for a wander. Not straight away, as it’s hectic, but towards the middle afternoon on Saturday it dies down a bit and you get to check out the trading hall, have a bit of a chat and just generally have a better buying experience. You feel less pressured as you check through the boxes on the floor (which – as somebody who has dropped 3 stone in the past year – is a lot more easier experience on the knees). One such place is [The Gaming Newsagent](https://www.facebook.com/people/The-Gaming-Newsagent/) – a long time attendee that started as SegaMags, but branched out into all such other magazines. It was in one of these boxes and a bit of time for exploring I found this magazine. St Format issue 70, from May 1995. An immediate buy. When I said immediate, I meant immediate. I never bothered looking through the rest. ![](https://www.rhyswynne.co.uk/wp-content/uploads/2025/10/st-format-issue-70-1538x2048.webp)Chain Reaction from ST Format Issue 70 (image taken from [Atari Mania](https://www.atarimania.com/atari-magazine-issue-st-format-issue-70_192.html)) So what was so special? This small PD Game on the cover disk, Chain Reaction. A simple addictive game I played so much and stuck with me for a while. Here whas what was written about it. ![CHAIN REACTION BY: Stephen Taylor and Colin Whitehead MACHINES: All STs FALCON-COMPATIBLE: No MEMORY REQUIRED: 512K RESOLUTION: Low UNCOMPRESSED SIZE: 152K Getting started You must dearchive Chain Reaction to the root directory of a blank disk (it isn't hard-drive compatible). The MENU program does this automatically for you. About the program Chain Reaction is a thoroughly absorbing strategy game, which sees up to six players (human, ST or both) competing to ensure their atoms are the last left on the playing board. You take it in turns to place atoms on a grid, but each cell, depending on whether it is a corner, side or middle cell, can hold only a certain number of atoms before reaching critical and exploding outwards. In this explosion, the affected atoms explode one atom into each adjacent cell. If your opponents' atoms are in that cell, they become your atoms (they change colour) and if that cell now becomes critical it also explodes outwards. This results in some catastrophic chain reactions that can wipe other players from the board completely. And it's shareware Chain Reaction features colourful graphics and neat little sound samples to give it real atmosphere. Full instructions on how to set up the game are contained in the REACTION.DOC file, where you'll also find a justifiable plea to register the program for £5. If you want more games of this quality on your Atari, you'd do well to respond. (Caption next to the screenshot of the game grid:) Chain Reaction offers multi-player action that'll knock your socks off (before blowing you off the board).](https://www.rhyswynne.co.uk/wp-content/uploads/2025/10/image.webp)Chain Reaction from ST Format Issue 70 (image taken from Atari Mania) If you followed me online for a while, you’d know that this sounds a lot like a game I made. [Gone Fission!](https://rhyswynne.itch.io/gone-fission) was inspired by Chain Reaction (and a thousand other PD games, I’ve got an article in my drafts where I talk about all different versions of the game and everything cool that has happened post launch. This is another of those things to add to that post, in a fun coincidence. Anyway, weird kind of full circle on a side project that dominated this year., A Full Circle Reaction, Rhys Wynne, 01k77jhwcxrz2twfb141wadrhs.
