All of this ultimately falls into the “nice to have” bucket rather than the “essential” one. If you loved the base game and want a little more juice to squeeze from it, you’ll likely be satisfied with what you get from SEGA Villains. On the other hand, if you’re expecting a full-on expansion, you’re not really getting that here. It’s a good excuse to fire the game up again, and I will say that what’s here pays homage to the respective franchises quite well. You get some excellent new boss encounters, some new stages to traverse, and even get some new moves and looks for your trouble. I do wish the stages were a little more fully-realized, and it’s disappointing that the only Sonic stage is reserved for the climactic boss battle. SEGA Villains isn’t all it could be, but it’s enough.
