Peter Molyneux gave us a look at how the online co-op in Fable 2 will work today during the E3 conference. He revealed that Fable 2 will not use any sort of lobby system, but instead will show purple orbs in certain places in-game, that players can walk up to and invite friends to join them at any point. Peter talked briefly about how the actions of the player effect the surrounding world. Towards the end of the preview, Peter said that players invited into a co-op game can interact with the world, and that co-op players can even get drunk in-game together!
