funny I was just coming on to these forums to express my displeasure with the lack of this feature.
I tried it last night with my wife. We wanted to play against a friend of ours on live. We were local, and he was on the internet.
When I hit the xbox live option it said there were two accounts signed on and only one of us could play, so we even had to sign the other person out to get into the game. I then tried to sign back in after we created the room and had her invite me. It sent the invite, but when I accepted, it would not let me join. So sadly only one person can play.
I don't quite understand why. I mean it makes sense in a game like uno or hold'em where you could see the cards, but what's the difference here?
So now we have to take turns playing online which is disappointing because that just means we won't really get to play against each other unless it is 1-1.
