ClassicRun Journal
A personal high-score and completion tracker for retro and arcade games that logs each attempt, stores the input replay file, and uses AI to write a post-match breakdown of strategy, mistakes, and milestones like Tetris's level-255 rebirth.
Retro gaming completionists and classic-game speedrunners who play the same NES/SNES/arcade title for months
- Replay-aware match log that ingests FCEUX, RetroArch, and MAME movie files and tags every milestone (max level, score, time)
- AI match commentary trained on classic-game strategy guides that compares your run to the canonical approach and the speedrun meta
- Personal 'game completion' dashboard tracking every system you've attempted and your furthest verified state (e.g., 'Tetris: level 162 — 38 levels from rebirth')
- Shareable trophy cards and a private leaderboard for friends so solo attempts feel like a community
The Antithesis Tetris post shows that 'seeing all of a game' is a powerful motivator for a meaningful subset of gamers, but no tool today treats that quest as a first-class project you can track and share.
Multiple existing tools show real demand — High Score Tracker on Google Play targets retro arcade scoring, RetroAchievements tracks classic-game achievements, CheevoTracker serves the completionist niche, and Speedrun.com/LiveSplit dominate the speedrun community.High Score Tracker - Apps on Google Play ↗RetroAchievements Tracker - Apps on Google Play ↗Home - Speedrun.com ↗
Not wide-open: RetroAchievements, CheevoTracker, completionist.me, and LiveSplit already cover most of the tracking+replay+leaderboard surface for this audience, though none bundle AI-written strategic breakdowns.CheevoHunter - RetroAchievements Completion Tracker ↗completionist.me ↗LiveSplit ↗
Speedrun community tools (LiveSplit, Speedrun.com) are free and open-source; retro gamers are notoriously price-sensitive. RetroAchievements' paid tier is the rare exception and is feature-gated rather than AI-driven. Hard to extract willingness-to-pay for AI analysis on tiny arcade runs.LiveSplit ↗RetroAchievements Tracker - Apps on Google Play ↗
Retro gaming market is large and growing — $3.12B in 2024, projected $4.18B in 2026, with North America alone at $1.19B — and completionism/speedrunning are durable subcultures unlikely to vanish.Retro Gaming Statistics 2026: Market Size & Player Data ↗Retro Gaming Console Sales Statistics 2026 - quantumrun.com ↗
Replay file storage is easy, but input-replay formats are wildly heterogeneous across NES/SNES/arcade emulators (FCEUX, SNES9x, MAME, RetroArch all differ), and getting an LLM to produce a useful 'strategy critique' from raw button inputs plus a screenshot is a non-trivial multimodal problem.LiveSplit ↗
