For now, there is something interesting in playing all the races. The only exception is high elf - they are almost the same as gray elves, but a bit weaker. The same skill set, very similar starting stats, the same very high age range - all this makes player choose gray elf in almost all the cases.

I think high elf should be made more different than their cousins by adding a skill or two (maybe alertness, which would make then really a good gray elven wizard alternative) or by making starting stats difference between them and gray elves bigger.
