whatever it is, it looks amazing... i was never a big metal gear fan though... i played and beat the first two, but barely played the 3rd one, and didn't get far in the 4th one... it's a series that's worn thin on me... too much dialog, not enough action... i hated sneaking around for 5 minutes, then watching a 20 minute cutscene, sneak around a little more, then watch a 15 minute cutscene...
kinda got tired of it... it looks interesting, but it's not something i am gonna play if it is indeed metal gear solid 5... perhaps if it's a spin off type of game and keeps the phantom pain name, then maybe...
this is the most convincing evidence i've found... phantom pain must be a project name, not the actual game name... meh, another metal gear...
