Yeah, except for those of us that like the Metal Gear series and have played it since the original. I just want a cinematic game not a movie that stops to let you play for 5 minutes before the next movie starts. We don't even know if that's the case, it's just my concern since it's requiring so much space and because it's the last in the series.
