Infastructure is where you connect to other PSPs over the internet using an access point (like a hot spot). Ad hoc connects directly to other PSPs within 150ft without an access point. Infastructure is in deed much better, and no where did R* say it was ad hoc. ON their LCS site they say it is simply "wireless multiplayer." Even if IGN said "Ad Hoc," the game might not have been a final build or they didn't get to try out infastructure mode. Even so, we can still use ad hoc over the net by means of X-Link. (Team X-Link site fools your PSP, PS2, GCN, or PSP into thinking it's playing ad hoc or system link, but 'tis really online!)
