Don't mean to get a little off topic but I didn't want to start yet another PSP thread.
How does the multiplayer work anyway? Do you have to pay for another online serivce or something?
I'm thinking about getting a PSP for the road but how does it get online? With the N-Gage you have to pay for internet service for the phone to get online (mine is $25 a month unlimited but it also includes web browsing, email and text messaging) and of course the n-gage is an atari 2600 compared to the PSP.
The PSP requires a wifi hotspot to use online, and at the moment, it can't deal with those that you need to log on using a http page.
I guess that means that you're limited to home wireless for now.
You can play against others in the same room using the ad-hoc wifi mode.
