There was a BIG problem with KOTORS combat stats display for hardcore RPGers, the stats of actuall rolls and other related hints/stats are not directly shown on screen. I know you could see it deep down in the dialogue menu, but then you can't make use of them during combat, that the point of having stats.
KOTOR2 could address this with an option that let people see roll stats/combat info with exented infromation GUI, like in good old Baulders Gate.(up down arrow on the right of dialogue box)
