ah dude others may say different (the elder scrols purists),
but i dont know any of the lore, im starting to play oblivion to maybe get the feel of it, but im a huge fan of fallout3
and thats why im here coz bethesda make great rpgs.
i dont think u need to know much, itll tell ya wat u need to know ingame.
but learning about the lore wont hurt.
im planning on learning sum myself.
but playing oblivion i dont know any previous lore but i sure am enjoying it..
:)
btw the creators have said that u dont need to know any lore or ever have played a TES b4, its accessable to every1
