I'm probably going to play as Jak first since I already played him on the kiosk demo and own. Plus, I want to win the first match I play. I'll probably play on Stowaway first too.
I might start off with PaRappa in his story mode, since I was most comfortable with him in the beta. Then I'd go on to who I REALLY want to play as first: either Nathan Drake or Cole MacGrath.
Not sure about stages, but I'd prefer my first match to be on something other than Hades or Metropolis.
since i played as sly in the beta (and demo) i'll be starting off as toro.
stage?? i don't care (but not hades or metropolis)
