Metal Gear Solid should just stay dead.
It became an awful series with 4. 5 and PW were just awful. The story became nonsense and then actually ended, but then felt the need to stupidly retcon and answer things needlessly. Probably because Kojima lost all interest and is maybe a hack... But either way, he never found someone suitable to really carry the series. The games need a refresh, but they also need someone with an actual personality and unique vision. That will actually come and be creative with the series. Not be afraid to break free from an oppressive canon.
Remakes are boring for this series. The old ones are perfectly playable and look fine. As talented as Bluepoint is, they also miss some of the aesthetics in all of their Japanese based games. They aren't going to capture Shinkawa's art are just Kojima's team's aesthetics.
It's dead. The creator moved on and was done without even before. And this was a series that had a real personal touch. If you want to make more MGS games, you need to find a team that is willing to really push ahead with MGS. Not be worried about annoying fans crying about canon, not be tied to doing everything MGS has done because honestly what even is that? You need a team that really wants to make a NEW MGS game. Good luck with that.
I'll take whatever Bluepoint does because I'd like to play MGS on modern hardware, but I won't be excited. The series is dead.
