AFAIK, there are only three races that are remarkable somehow.

1. Elf. He has an XP bonus. The bonus results in higher character level.
2. Omphaaz. The Omphaaz regenerates mana extra fast. A hot candidate on a mage.
3. Pixie. He is dodging attacks very successfully. But a pixie is buggy. He seems to dodge his own spells so that it's a big problem to cast defensive spells on a pixie. At least, as long as you play a solo pixie.

I daresay that all other race differrences are either unessential or temporary. Once you improve your abilities and once you get some training in skills, all race differences virtually vanish. Only an elf and an omphaaz will never lose their advantages. Even a pixie vill "vanish" when we start speaking about highly agile roles like a zenmaster, an assassin, or a ninja.
Therefore, think about an elf or an omphaaz. If you don't want neither an elf nor an omphaaz, then it doesn't matter too much which race you select.
