NyxQuest will be a wild card for you.
Looking for a great downloadable game from PSN.
No FF7 or Castlevania please.
Uhhh, there's a new game out that looks awesome on psn but i can't for the life of me remember it's name.
Warhawk is a great PSN game, i'm downloading it later this week, it's a shooter so, idk if that tickles your fancy.
Last guy is also kinda good, Ratchet and Clank: Quest for booty is fantastic as is WipEout HD. There are also some fun casual games like Super rub a dub and pytoru (sp?)
What might also be worth a check is 1942: Joint assault and Red Baron arcade.
1942 is really fun with friends, but kinda hard, Red Baron is pretty average, but the free demo has the online mode on it, so us PSN users could always mess about on that.
Ricky, get yourself Burnout Paradise on PS3, cannot go wrong with it.
Kerotan, your brother might like Overlord.
