I haven't yet. When I started, ( I can still remember it as if it were yesterday....) Idecided the bestway to go about would be to give my character a level amount of all traits. You nee strengh and constitutin for battles, and Wisdom and Intelligence for regaining memories and successfully pulling the wool over oher characters eyes.
I ave also played BG and Fallout 2, but I found BG a bit off putting, as it was really REALLYdifficultto stay alive in the gam for more than fie minutes without gting hediouly slaughtered.
