I've always been a fan of the Settlers games. From what I understand they do well in Europe, but not so good here in NA. Kind of a bummer as that means we miss out on some of the expansion packs and such.

No One Lives Forever is quite possibly one of my favorite shooters ever made, yet no one seems to remember it. Great story, great gameplay, and the subtle (and not-so-subtle) humor made that a fantastic game.
