Just wanted to add to the above - PS ruined me for other games for life. I'm afraid nothing can really compare a multiple-galaxies hot drop into a red alert base with 2 minutes left on the clock. Talk about adrenaline
Knowing that these two minutes are the culmination of an entire 2 or 3 hours of fighting between hundreds of players and being that linch-pin on the last ditch effort to turn the tide ... it's epic on a different scale. A scale that is utterly out of reach for any 16vs16 players arena game. Or any single player game for that matter - regardless of its scripted actions and cut scenes. Knowing that the losers are real life people and not just a spawned instance of some AI makes victory that much sweeter and defeat that much more driving to vengeance.
So yeah ... these past 8 years you've been wasting your time on *games*. It's time to graduate to something a little more ... serious
