Actually, as I was going through my wishlist, I just realized I only have 2 more XBox (original) exclusives left on my wishlist: Stubbs the Zombie & Yager. So I guess that's a goal.
The other exclusives I've got already: Arx Fatalis, Chronicles of Riddick: Butcher Bay, Crimson Skies, Morrowind GOTY, D&D: Heroes, Fable: Lost Chapters, Halo 1 & 2, Jade Empire, MechAssault 1 & 2, Ninja Gaiden, Panzer Dragoon Orta, Star Wars: KOTOR, Tecmo Arcade Classics, & WWE Raw 1 & 2.
