Command & Conquer: Red Alert 3 is a wild ride through an alternate history where the Soviets travel back in time to mess things up. The campaigns are fun and cheesy, with over-the-top storylines and wacky units like giant robots and psychic schoolgirls. The co-op mode is a blast too, letting you team up with a friend to conquer the battlefield. The graphics might be a bit dated now, and the pathfinding can be wonky sometimes, but overall, it's a classic RTS game with a ridiculous sense of humor. If you want a strategic base-building game that doesn't take itself too seriously, this is a must-play.
