I bought the Baldur's Gate Enhanced Edition and on the store page the description says it includes the 'Original Saga' howver I can't seem to find a way to access this Original Saga. How to I play it?

yea, figued it out by some googling. Still, I think they should send you an e-mail or something...also, do you know how or if you can delete forum posts? No need to get my inbox spammed with answers to a question that's be resolved

No, there's no way to delete the post, but it's unlikely that you'll get further replies to the post anyway; a question that's been marked "solved" and has a solution doesn't really lend itself to further discussion, particularly since there's no room for differences of opinion on this topic.

Edit: Also, leaving the post up can be helpful in case somebody else has the same question.
