Not yet! :P Can't say I haven't thought of it. I'll probably keep it as a lot of my longtime friends are on there...been waiting for PSN to come back online. If not, well, I guess I could sell it. Dunno if it would be worth much with the mess Sony is currently in though lol.
Not quite sure yet, lol. I was a PS3er and recently got an xbox last week. I'm kind of a noob. I've been playing COD: Black Ops, some Fable II, and got Gears 1 and 2 today. Been fun so far. I hope to add more to the collection.
