3 Big Mistakes:
1) Only third party exclusive were MMO's - lame
2)Paywall- I already have + and it's more than worth it but it sucks for some people AND if it's mandatory for multiplayer I expect the free stuff to go down.
3)Not dropping a mic when they shotgun blasted MS right out the door.
If you haven't seen the Used Game tutorial Sony made, see it. damned funny
