I think something like the game Frontier should be made Multiplayer, and while your travelling, you can encounter other players. (jsut remove or modify qeusts a bit.)
Its a newer game, but I think ti has the potential.
We need Multiplayers. Thats agreed. But poker? I guess its good, and i like it, but if AG were to add games like that, they'd need an age restriction thing (say, 17 years).
