Stone full plate? Some items don't make sense unless you restrict materials.
After playing a bit more I am more convinced that giving classes bonuses/penalites rather than strict equipment blocking would be better. I don't have to be a knight to wear heavy armor, but if I'm not trained for fighting in armor, I would actually be penalized (lowers peed, reduced effectivenss) while those that are trained would not.
EDIT: I have to say that I prefer the old system of actually traveling around, going form town to town. Not that I mind dungeons, but they seem like a nice extra, not like something that should be core.
Travling and ambushing or being ambushed (depending on party size. Big enemies groups are easier to detect and evade. Smaller party hides more easily) and random encounters were good.
EDIT2:
Here's a big suggestion - instead of a turn passing in sex every time something is selected, have it only pass when you click on PASS TURN. That way one can get away with less turns, but far more controls. Also setting up big orgies becomes possible. You can easily run out of turns before you arrange half the actors.
