Got 2 360s linked together via 75ft ethernet cord, but when I choose system link on each console, neither can see each others game? One console I select to create game, and the other one I selected to join game but I dont see the game in the system link screen. WTF!!

Are you sure its a crossover ethernet cable?

Do you have your console set to DHCP in network settings. That could make a difference.

ok. figured it out that I had one console with an updated version with hdd, and the other console had no hdd so both games werent same version, since one had been updated through xbox live. Now that I downgraded version by cleaning cache on hdd....both consoles see each other but can only play one player per console. Is that the way the game just is? On halo3 its 2 vs 2 with a split screen on each console. Does anyone know if cod4 can do this also?

Unfortunately COD4 does not have guest play as in Halo 2 &3, or the previous COD games. This is very sad

The lack of guest game play is an obvious shortcoming of a great game.

I have always considered xbox live game play to be ample for my game play needs. [Must have a good host] Although I have only system linked once it was enjoyable but the proximity of your opponent leads to dishonest game play.

I did not have any problems with settings or Ethernet cables and I think that system link gaming is enjoyable and removes the excuses and problems of lag and latency
