Strategy Games
116Strategy games ask you to win before the battle starts — through positioning, build order, or long-term resource planning. Tower defense, turn-based tactics, and management puzzles all land here. The web has a deep bench of indie strategy experiments, often more honest about their mechanics than bigger-budget cousins because there is no tutorial budget to hide behind.
