You know what else is a fun game? Stacking is a fun game. Maybe you heard of it—an Xbox game in which you play a little Russian stacking doll. And you gain new abilities by combining with other dolls. It's a fun gimmick. Special bonus for having a silent-film aesthetic. (Though I kinda wonder what the game would have been like if the dolls had somehow lip-sync'd to voice acting... I suspect it turned out better the way it did.)
