I bought Skyrim just by itself on Steam, no DLCs. I'm level 59, walking through Falkreath, when a guard just talks to me and starts the quest. I entered Dayspring Canyon but haven't done anything else, so who knows, maybe it's all buggy or something but it seems that I can play it so far. I'm not really complaining, but it's strange. When I go to the page for Dawnguard on Steam, it doesn't tell me I own it. I think it would say that I had it even if it was given to me as a gift. Anyone know what's up with this?
