Expansions are worth it; even without the expansions there are quite a lot of mods available, some of the bigger, better ones require at least Dawnguard. It's just an amazing RPG, even without the expansions and i've soaked... about 1000 hours easy into it, that doesn't include modding stuff. In other news, I got Sleeping Dogs and Counter Strike: GO. I'm not a counter strike fan, but my mrs. is a fan, so I had to buy it for her. I'm a fan of RPGs and Adventure, not FPS and military simulation.
