Halo 2 most be the first game that impacts on both a "real life" social life and a "online" one. Although i do question why you'd ever need 100 friends on the xbox. I know with it's more usable voice chat (in my experience) I suppose having people you know is useful and prevents you from listening endlessly to, for lack of a better word, idiots either constantly hurling abuse at you or whining that you cheat etc. But who needs a 100, now that would make sense on that mag game that's coming out (for ps3)which apparently will be able to have 256 online players per map but even then you'd never be on line the same time
