SAKANA FUGU ULTRA vs. CLAUDE OPUS 4.8 RESULTS
Prompt: "build a really high quality single html file subway surf game with three.js"
Sakana Fugu Ultra:
Tokens Used: ~96k ($7.80)
Time Elapsed: 24 minutes
Issues: lane switching felt slightly delayed, camera shook too much at high speed, coins were too easy to farm, no hoverboard, no power-ups, weak Subway Surfers feel
Claude Opus 4.8 Ultracode:
Tokens Used: ~910k (~$36.60)
Time Elapsed: 82 minutes
Issues: got stuck once fixing collisions, restart sometimes spawned the player inside an obstacle, early game was too hard, train patterns were more polished but less balanced
In terms of visuals, polish, gameplay feel, and overall “real game” quality, Opus won.
But in terms of speed, cost, and raw execution efficiency, Fugu on Opencode was way ahead.
So the real question is:
Would you rather pay $7 for a fast playable prototype, or $36 for the better-looking game?
