Hey, have you picked up SOCOM for the PS2 yet? It's been loads of fun so far. I really like the headset setup they use...You can order your teams around via the headset mic(VR is very good), and all your teammate responses comes through the headset, but the enviroment sounds are through the TV(or stereo) speakers.

Also little trick, you don't *need* the PS2 broadband adapter to play, several of the usb<->ethernet adapters will work with it
