Halo 3 is deffenetly one of the best games around. My brother and I play it at least once every day on live. We dont do ranked matches as the people there tend to have no lives. But we play Infection games constantly as those are fun as hell with a bunch of people. My brother and I made a really fun one called "SANDY SCAB" and every one loves it. We also made a new one called "FROZEN SCABY" Its a lot harder and much faster pace then "SANDY SCAB." But any way. Yeah Halo 3, Gears of War, Tiberium (which is comming out here shortly) Chrome Hounds, COD4, ect, ect, ect. You cant go wrong with a 360. Oh and make sure you get that warrenty.
