In this thread Iamtim asks about what benefits to give humans if he removes level limits. As I am not a fan of level limits myself I am interested in the answer.
Later in the thread timmyd comes up with an idea to give Human a XP bonus. He suggests +40%!. While I think that is a bit excessive I think set to about +10% is a great way of making human attractive compared to their demi-human counterparts.
+2 to any stats of choice (can be split to +1 to two stats)
+10% XP Bonus
This can be combined with the +5% prime requisites bonus for a total of +15% to XP.
The XP Bonus seems more in the spirit of OD&D than any of the other solutions I been mulling around in my mind. Thanks Timmyd and the rest of the S&W forum crowd.
