I'm planning on getting another PS3 for my office. I was curious, do the 2 playstations network to each other? Do they recognize each other? Will I have to have 2 seperate accounts? Thanks for the information.
You can play some games that have LAN game multiplayer mode, for example, Unreal Tournament 3. However it could be difficult (or even may be impossible) to make both consoles work together with a single router using the same internet IP address so it won't be easy to access PSN unless you have separate internet connections for both consoles.
