I think the Halo's will stop after three and you probably will play as the arbitor and master chief again just like Halo 2.
Favorite Games:
1. Gears of War (Best Game Ever!!!)
2. Final Fantasy Series (FF7 forever)
3. F.E.A.R. Series (Very Creepy and Good)
4. Guitar Hero 1,2,&3 (Less Talk More Rokk by FreezePop...rock on!)
5. Rachet and Clank Series (Favorite Lombax and little robot duo)
6. Call of Duty Series (Take Cover and Kick Some @$$!!!)
