So, like offering a bonus die or power to a future roll for a PC using his own flaw against himself? That was my solution, anyway. Fate does this too with Compels, if I'm not mistaken.Old school gamers are always complaining about "just roleplay it," but I have rarely encountered anyone who deliberately handicaps their own social, insightful, or reasoning skills when playing D&D. And I think that offering some kind of in-game reward for doing so would probably make people more likely to do it. And it might be "better" (or at least more transparent) to have a system like that rather than simply declaring "people should/will do that."
I don't think that you need a separate system for mental encounters. Especially if the base game is flexible. But it would be a nice change of gears to do something different than Attack Rolls For Everything.
