i would like for (and predict!!!) a new school system that a player has to make a choice in being a part of. for instance, right now we all have the same classes that we can take.. right?
well, what if there are ... i dont know, 10 different classes that we can all take. these classes all affect different areas of the game. some are dex/crime related, some are acc/range related, some are str/melee related, some are balanced/fighting related... whatever!
in any case, i think it would be interesting if you have to choose a concentration of class and become more proficient in that area. maybe that would be an extra element to the game play. it would ALMOST be like a "class" in an RPG (warrior, mage, archer, w/e), but it wouldn't be THAT significant. in the long run, it really would be significant, but if you are ranged proficient, you could probably still pwn some face with an axe.
or maybe you could just pwn up some crimes and stuff.
