Playing online

[Larkspeed]

I have a PS2 my son has a PSP and a friend of mine has a PS3

What I would like to know is what games there that are online playable that I can play with my son or my friend.

Me and my son tried Test Drive Unlimited last night and although it looked like we were both connected to the same place as far as numbers of people connected went we could not see each other.

well in TDU we can add each other to our friends lists but thats seems to be about it

yes thats it

we were online together and he added me to to his friends list, I saw the invite come up on my screen and accepted it but we could not find each other anywhere on the map

---edit---

For clarification I was on PS2 and he was on PSP
