I don't have a PSP, though I'm thinking of getting one and I'm wondering how does the multiplayer work compared to the DS. Can you only battle with people in your vicinity using wireless/ad hoc mode, or can you go and battle online players via wifi well? If yes, is it more stranger-friendly than the DS? As in that you don't have some multiplayer modes/features locked when the online player isn't on your friendslist or something like that. I've read that the PSP has some kind of an "Ad hoc party" where you connect online with the PS3 and search for other players, but it would be really annoying if you had to have PS3 as well in order to be able to play online with others. Also, is there some kind of a list of which games can use the online wifi multiplayer? Do popular games like Patapon 3, Monster Hunter and others have it (if PSP has it like the DS and you can use it without PS3)?
