There are quite a few games that do not allow mulitple clients on one computer or a single ip address (behind a router). Then there are the games that only allow one console per person according to ToC's, mainly free or pay for ingame money games do that. Just some food for thought, I'm just looking for a list of tried and tested Mboxing games. Some games may allow you to run more than one console but not on the same computer, based on programmers memory locking requirements. These are nices to know when looking at new games to try.
