Umm if you wanted online FPS-ing wouldnt you have a PC anyway so its not new, well the "house robbery system is probably the same how you rob store clerks in GTAVC. And Im still more interested in Metroid Prime 2 than Halo 2 and anyways I dont have an Xbox and I dont plan to buy one anyways since I know I will have fun on my DS more when I buy one heh. Halo 2 looks good but it will be like Doom 3 was it looks nice but it will play the same old way(except you cant use gernades while dual weilding) and Halo didnt keep me THAT excited while I was playing I kinda found it boring especially The Library level and the flood sequences. Also GTA VC was good but I think I had enough of GTA for now.
Anyways, I think I will have more fun with VJ2, Paper Mario, Baten Kaitos and Prime 2,MGS 3,Mario Tennis(wow I need to get a job) and FF1&2 than I will with GTA:SA and/or Halo 2.
