im reseaching this cus comcast is starting to put a limit on how many Gigabites of data you can use a month, with in my opinion sucks. But i think they are still trying it in Oregon or something like that. and i was searching this too, and ive come to find a few topics that a regular game of halo 3 for about 3 or 4 hours use like 5gb. i live in the U.S. and this is the first time ive heard of this, and i think this is retarded.
