In Obivion you played Imperial
In Skyrim you played Nord
etc
I never played Morrowind but i will admit i played an Imperial in Oblivion and a Nord in Skyrim, but i feel i enjoy Nords more than any other race now and its very possible i may play a Nord mainly in future games also, i find however that i would rather play a character that can relate to the setting more however so i can immerse myself more easily. If the next game is in Eleswyr i would probably create a Khajiit and etc. If i ever get Morrowind (which i probably will) i will probably play a Dunmer, this might be because i sort of mainly feel i havn't given the other races a real chance in the other games and so now its a chance i can in their natural province...
But im confusing myself now, what do you guys do?
