Monopoly Streets

same problem here....want to play a game with my gf on the same xbox vs her familiy on other xbox on xbox live...but we can only play with 2 guys at once and no guest acc. on both xbox................looks like no guest acc. are allowed.

that is really shiittyyy.....cover of game says solo 1v4 Players and 2-4 via xbox live...but nothing that u can not use it crossed.

I give the game back because no information about that issue is given.
