Ok, I'll concede that there have been AI improvements since Deus Ex, but I didn't think it was all that bad for it's time, and I don't think Half-Life's AI was that much better.
Well, I disagree that the endings were terrible. I'm not sure what you expected besides short cinematics.
Pretty much, only a graphics whore would say that.
True but would you worry about sales you won't get or rather worry to get the sales you could get. Fact is you make money by selling things, not by running after thieves.
