Meeh, I liked Oblivion, Fable series, and some other things considered RPG's, but I didn't like Fallout either, neither did I like Mass Effect.
Somehow I think a RPG should be set in a historic setting, with only Melee weapons, and magic as your possession. I feel using advanced guns, and whatever is out of place, it doesn't feel right for me. I gave fallout up after a small 8 hours, of only walking, walking, and walking without actually having fun in killing and such. And Mass Effect was too much Shoot, duck, shoot, use the force, duck, shoot.. and uughh, the perspective was soo bloody annoying.
