We gave the same prompt to vanilla Claude and three Godmode tiers. The difference isn't subtle.

Identical environment
claude-code — prompt
$Create a polished Tetris clone with hold piece, ghost piece, next queue, scoring, levels, and a local leaderboard.
The test: One prompt. No follow-up. No clarification. Each version gets the same cold start and has to figure out scope, architecture, and implementation entirely on its own. The metrics below are from real runs.
highNo test suite — gameplay logic, collision, rotation kicks all untested
mediumNo T-spin detection or back-to-back bonus scoring
mediumNo line clear animation or visual feedback on tetris
lowNo audio — line clears, locks, level ups are silent
lowNo save/resume mid-game on refresh
lowLeaderboard has no clear/reset option

Note: Higher token usage and cost for Godmode tiers reflects deeper execution — more context loaded, more tests written, more security checks, more verification passes. You're paying for quality, not verbosity.
See for yourself.
Same prompt. Same model. The only difference is the skill. Stop settling for first-draft output.
