Just a thought for someone purchasing this it game...,
Verified Purchase(What's this?)
This review is from: Bioshock [Online Game Code] (Software Download)
This is one of my favorite games, with that being said, it is old, and you do have to put some effort to get it to run. However it is WORTH the effort. Don't give up and check out a few forums, audio and compatibility modes seem to be the main issue so start there first. Hope this helps.
