i play my paladin from bg1, and he begun the game with the following all 18's except for his 4 intelligence. i didn't roll too much to get this high stats (about four or five times), and now my character has mostly 19's. (i still think i should have used all the tomes of wisdom on him, he would have had 21 wis...)

i DO, however, roleplay him that way (as far as the game allows, since roleplaying is really hard in a computer game with fixed answers to all conversations).
