1. Halo 2. I've bought in totally. Launch day will be orgasmic.
2. Jade Empire. Kung-Fu bitches!!! In a RPG!
3. Fable/Conker. Conker I believe in. Fable I will buy and hopefully be convinced by.
A ton more as well, Xbox has a great 2004, my favorite line-up (not that I don't want everything on the other two).
