Bioshock 2 and Dante's Inferno. Loved them both to bits.
Bioshock 2 had a more emotionally involving story, in my opinion. It didn't carry the same weight as Bioshock 1's story did but I still was very immersed and got choked up at parts. Also, the combat is much better and I had more fun with it than Bioshock 1. Bioshock 1 was supposed to be scary and it was, Bioshock 2 was supposed to be fun and it was. It did everything I wanted it to. Based on its own merits, the game is great.
Dante's Inferno was a great, but flawed, game. I actually liked the game more than the only God of War game I played: Chains of Olympus. I felt that the games were so similar I could only judge them based on story and characters and environments, and that is where Dante's Inferno excels to no end. The story and dialouge is lovely, the characters are interesting and a bit gruesome, and the environments are sickeningly great. One can tell that a lot of love went into the game; I just wish people didn't compare it to God of War so much and just looked at the game itself.
