i think it would be interesting to catalog all the current ps3 games that allow you to access parts of the xmb in game.

music access:

friends list/messaging access:

Rainbow 6 vegas

Unreal tournament 3

Timeshift (demo)

Warhawk (buddy list/game invites)

PS store integration:

Warhawk

Super Stardust HD

the idea is to take my list and add game titles you've played that allow for any type of in game xmb (or have some sort of in-game store) access.

Hopefully soon all of them will.

RFoM has friends list and store access i think.

Warhawk let's you message in game? I did not know that, and I've had it for months.

You cant message IN GAME with warhawk or resistance.

you can't access the xmb during warhawk at all

more specifically i guess, warhawk lets you see your buddy list and join games that your friends are in. there is no in game messaging, i just put it in the same category.
