I really think that comparing any Elder Scrolls game to a Gothic game and claiming they're similar is kind of insulting to Piranha Bytes.
Both games are quite different. Again, if you like Oblivion, I don't care. That's great. If you can't see the difference between them, that's okay too. I'm just stoked that Risen 2 is coming out and I hope they don't fuck it up and try to dumb it down. That's all. Carry on...
