User blog comment:Gekkou30/SC Blacklist and Phantom Pain Similarities?/@comment-10613757-20130613041939

Firstly, as Jim Logan said, GZ and PP are one in the same. I don't think they're deliberately taking mechanics from each other (in MGS's case, I don't think they're taking any mechanics really... except for the night-vision goggles in GZ maybe). Both seem to be top-notch and unique in their own way (GZ/PP moreso IMO). GZ/PP also seems to a lot more free-roam and is set in a rural environment, while Blacklist has more urban combat (as it usually does).

When Sam Fisher starts doing the belly-crawl, then we've got a problem.
