BioShock 2
BioShock didn't have much of a story in the traditional sense - other than Atlas, and some business with Andrew Ryan, it was more of a Metroid Prime affair: unraveling the mystery of Rapture. Forensic, really. The story was the setting, and it worked great. But BioShock 2 has the same setting.
As such, it invents a new main antagonist to try and re-focus the story, but Lamb really can't compete with Rapture, and I already know all about Rapture. Not that this is a bad thing, exactly. Rapture is as moody and atmospheric as ever. The formula still works.
BioShock was a good game, and BioShock 2 is more of it. It's also, at least starting off, surprisingly challenging (on Normal). So far I don't like the Big Daddy's drill and rivet-gun armaments as much as I would real guns; but the game is introducing new stuff to me at a good pace, so maybe something better will come along soon.
