Optional rooms that ask whether the player wants power badly enough to bleed for it.
Curse rooms are reward spaces with explicit entry costs, hidden costs, or dangerous tradeoffs. They work because the player chooses the risk and therefore owns the consequences.
Example
The Binding of Isaac's curse rooms charge health for entry and may contain powerful items, enemies, or nothing worth the price.
Why it matters
Curse rooms matter because they crystallize roguelike decision-making into one door: safety now or power later.
