I've always been a bit uneasy about intelligence being the sole contributing stat to how many skill points a character gets. It makes sence for SOME of the skills, but for some others, it just seems weird...
Think about it in the case of a powerful Orc warrior, who live on the land. He might have an INT of 6 or less, but surely he could be good at many "skills" which might not have anything to do with his level of intelligence, for example swimming, riding, climbing, jumping, balancing, intimidating, listening, spotting, survival, and so on.
Some of these ok maybe you CAN explain it in a way where intelligence plays a role, but some things make no sence in that regard (especially listening, spotting, and jumping).
I realise that SP's are effected by INT for game balance reasons, but it just seems strange. Imagine in the case of a int 6 Half Orc Fighter... only 1 skill point per level???? He can either jump far, or have good hearing, or have good vision, but he is "too dumb" to have all 3???
Another thing... anyone else think its a bit strange that the Intimidate skill is affected by only your charisma? For some reason I always imagined a big hulking snarling rude Half-Orc would be able to intimidate someone more than a charismatic halfling bard...
