My only request is that the game mechanics to be flexible enough! What do I mean by that.
In BG series a wizard could not even hold a sword or a bow. Of course there were ways to go around this but the penalties were too steep, e.g., for an elf it should only possible as fighter/mage.
One of the reasons I loved IW2 was that they had 3E rules that allowed to use any weapon you wanted. Imagine a female elf wizard with a great axe (I mean you could spend the feats to actually hold the weapon without penalties)... now of course she would be never as good as a half-orc fighter but that is not the point; it is afterall an role-playing game, right?
So my only request is that the game mechanics are flexible (or not too restrictive)!
