Shu is awesome, dammit Aiden!
Well, naturally... I think what we'd have to do if we did do a Romance of the Three Kingdoms RP is just have characters on one side fighting on two fronts... and probably the 'prelude' stuff.
Wouldn't be anything like Shu, Wei, and Wu, but something... similar, just so that we don't have people like Aiden getting furious if our army is dressed in green. :)
