I was just about to post about this very subject when I saw this post...
I am looking at getting a new system in the next few weeks and was not sure if this game ran on Win 8.
My current system does not cope with running Shilovo DLC so I have yet to play more than 30mins of it since
I purchased it....
Hence the time to upgrade to a new system for all the new games coming out, including Mius!
