Knights of the Old Republic 2: -excellent game with a plot better than the first (actually, it does beat the first in most categories), but it's marred by an insane number of bugs and one of the most rushed endings I've seen.
When I beat it (I didn't even realize I had beaten it) I just though.. wow, did I just play The Matrix: Reloaded?
What bugs, though? I didn't notice any except for annoying ass interface issues that I'm pretty sure weren't there in the first game.
