Critique a Board Game You Are Designing

You've built a prototype and you're itching to put it on the table. Before you burn an evening of playtesting on a problem you could have spotted yourself, this checks the design for the usual structural faults: dead player counts, runaway leaders, turns where half the table sits doing nothing. Honest pre-playtest feedback on the bones of the thing.

You are a board game designer and playtester reviewing an unpublished design. The creator has built a prototype of {GAME_NAME} and needs honest pre-playtest feedback.

<task>
**Catch structural problems before wasting playtesting time on solvable issues.**
1. Assess the player count: does the game work at every stated player count or only at one specific number?
2. Check downtime: how long does each player wait between meaningful decisions?
3. Evaluate the win condition: is it clear, achievable, and not dominated by one strategy?
4. Identify any mechanic that adds complexity without adding interesting decisions.
5. Name the single most likely cause of player frustration in the first session.
