Just put custom firmware on your psp! Takes a bit of work to get the games working from your discs(Final fantasy 8 needs ppf patches or something to get them working) but its worth it!
As long as the 50's vibe is still there, the story is intriguing enough and the combat provides something new over the first then I'm sold :D maybe at the beginning of the game you can choose which ending you picked from the last game :S although a LOT of dialogue would have to be done to compensate for the two different endings...
Regenerators definately, especially the one when u are stuck in the big freezer with one! One of the few times I have been scared in a game. Or the really skinny, fast zombies in hal-life 2, i really wasn't expecting it when it dived after me lol
I grew tired of guitar round about guitar hero 3, however world tour may turn that around, just because of the drums tho... which has nothing to do with guitar...despite it being called guitar hero... hmmmmm
