Is there a way to get it in your actual game library, like a game you bought on steam, or do you just use the add game feature..?
No because adding add-ons to it is a bit more painful
Adding add-ons to BL: Drag zip to add-ons folder.Adding add-ons to BL (but with steam): Drag zip to add-ons folder.
No, because then you can't get a steam alt for $4 on sales.
