Well, they do have lots of point and click adventures, like Syberia series. They also have RPGs like Avernum and the Aveyond games. I picked up the latest, Aveyond: Lord Of Twilight and think it is pretty good so far for a jrpg-style game.
And of course, don't miss Plants Vs. Aliens! they have other tower defense games, too, like Master Of Defense.
And I loved the Tradewinds series. Tradewinds Odyssey just came out.
