Summary: Bioshock 2 was buggy and took some effort to run. It would not run under dx10, only dx9(Windows 10). The gameplay was ok, but too short and not challenging enough. I wouldn't of bought this if I knew how hard it was to get to run. There are no returns for digital media.
Summary: I'm not sure why this is $5 cheaper here than on the Steam store, but it is, which is pretty cool. The DLC itself is a single-player story campaign that can take anywhere from 2 to 6 hours depending on how much you explore.
Summary: I'm a big fan of the Bioshock series. Minerva's Den is a nice addition. It had a balanced mix of a new playable area and additional features that include new tonics and powers. One thing I am a bit sad about, however, is that this content isn't added directly into the game.
