Do itttttt. Or just get it on 360/PS3 if you have either console.
I originally played Bioshock 2 at release on 360, because I didn't have a proper gaming PC.
Somewhere along the line I picked up Bioshock 1/2 in a Steam bundle sale and I would prefer to play Minerva's Den in the greatest way possible. First I have to install BS2 on Steam...
