I thought Microsoft was the publisher for xboxlive marketplace games? If so why do developers need publishers for arcade games? or does this just mean Bethesda will be porting the game to arcade
Anyway more to the point where the friggin hell is Quake Arena
Nah, you still get 3rd party publishers for XBLA games. Boom Boom Rocket was published by EA, for example. As was Portal: Still Alive.
My guess is that the publisher do all the legwork in terms of talking to MS and making sure it all goes through onto XBLA ok.
