Pay more attention to characters' traits and try to roleplay it just a bit more that way. If a guy is rash, do something illogical that might hurt your faction every once in a while. If a guy is really too cautious, that battle that looks like a cakewalk - well, have him pull back his forces. Lots of ways to get into things more, and lots of new stuff coming down the pipe too, but things like delayed music and such just aren't possible given the engine.
