#10 Borderlands 2
Gearbox built something unique with the first Borderlands. Though the game took heavy cues from Diablo and other action RPGs, the shift to FPS combat and outstanding art direction made for an experience unlike anything else on the market. For as good as it was, though, there was definitely room for improvement in the storytelling department. The upcoming sequel will seek to remedy that, bringing an added coat of polish to the strong gameplay foundation.
And if you're just looking for more of the same, you won't be disappointed either. Borderlands 2 a more diverse armory, four new characters and skill trees, and a broad patch of Pandora to explore, this time without any loading screens to break up the fun. A lot will be riding on the new character classes, three of which are still unannounced. Of course, the class we do know is the Gunzerker, a human tank that can dual-wield any gun in the game, so things will probably pan out just fine.
