Sony is bringing adhocparty to North American gamers soon so get ready! Why is this great news that you should care about? Got a PSP and a PS3 system? Want to play a game like Monster Hunter Freedom Unite online (of sorts) and play with your friends from across the street or the continent. Got Gran Turismo? Another great title that is designed to take advantage of this feature, again, expanding the game to new levels.
Check out the Capcom-Unity page on adhocparty here.
