I don't buy many PSP games, but I was just at Best Buy today looking around at the PSP games and was surprised at how many games *don't* support online play. I must have looked at 10 games total and out of all those, only 2 featured network play. It wasn't just adventure games and RPG games I was looking at either but ones that could really benefit from online multiplayer, like sports and fighting games.
Does Sony and the developers that make games for the PSP just not care about including online multiplayer to their games? Sure, almost every game includes 'Ad-Hoc' wi-fi multiplayer, but it's hard enough for me to find someone with another PSP to play against in person, let alone with a copy of the same game. Just don't understand why they can't make more of their games with network play (or whatever they call it).
And just a random observation....Sony REALLY needs to make it more obvious for people to tell which games have online multiplayer. Like put a big bright strip across the top like how Xbox games have. A tiny little bubble in the bottom back corner of the case doesn't cut it. And I still don't have any idea what the fuck 'Ad-Hoc' means other than you can't play online with it.
