I was wondering can you have guests play on xbox live? or just one person.

One person per xbox unfortunately.

is that true? can't you play mechassault with a guest logged in?

Before I rented it I thought you could play with 2 people on LIVE. I'm sooooo glad I didn't buy this. My wife and I would of had fun together on LIVE but without that feature I'm already bored with the game and I just rented it last night.

Yes you can, but his question was about Midtown Madness 3, not MechAssault.

yeah, that sucks, I have no clue why they do this... Ghost of recon, return to castle wolfenstein.... now this.... Don't understand what they are thinking.

Well it would weigh down the bandwidth while adding a member of the game who couldn't communicate. For games like GR and CW that seems essential. It'd be nice to have for this one tho.
