1.Duck Hunt - Seriously, if I had this game, I'd feel on top of the world. 2.Halo 2 - What's the point of an Xbox if there's no Halo? 3.Madden NFL 2002 - It was my favorite of the Maddens. And you need sports games. It can't just be all shooting games. 4.Elder Scrolls IV: Oblivion - It's just so addictive, everybody wants to play it. Also, the excellent graphics and amazing sounds work nicely in our home theater. 5.GTA San Andreas: It's a massive, addictive, and multiplayer game. And the multiplayer is mindless killing! What could be better?!
