Johan detailed a "Savage Gnome" Racial Variant in the "Character Information" board. This was a collaborative effort from both of us. If anyone would like to use Racial and class Variations for a character (current characters notwithstanding) discuss it with me and we'll work something out.
This Savage Gnome variant brings up an interesting point in the game: Environment. Races native to climates and geographies would certainly adapt to those conditions. Just look at how diversified the human race is.
D&D covers Racial Variants in the "Unearthed Arcana". However, some of the variations (like the Gnome) I think fall somewhat short (heh, Gnome...short) of their potential. This being the case, a player that is creative enough to make fitting variations is welcome to do so.
Another interesting racial twist detailed in the Unearthed Arcana is "Bloodlines" (pg.19).
Bloodlines Good!
