cool games???

Im looking for a good open world infrastructure game for my psp, where you can kind of roam but interact with real people over infrastucture, not the comps. plz help...

hmmm depends what you mean under interact.............

if you mean something like sims then i have no clue, but if you just want to play online with other friends from all around the world then i would say monster hunter is a good choice..... but i think to play online you need xlink kai and you can only team up with four other hunters..........i hope i could help
