revisiting takes away some of the nostalgia IMO... the upsides are that it introduces people to those games on a more modern level and possibly creates a new set of fans for the series..
but thats not to say it doesnt cost a mint amount of money and a good dev team to pay the game the respect it deserves
I agree he should remake both games into single expanded version with much bigger screenplay, more cinematic and upgraded gameplay. Each one can be its own chapter, like \Plant and Tank chapter in MGS2.
Metal Gear Solid 3
Metal Gear Solid Portable Ops
Metal Gear Solid Peace Walker
Metal Gear Solid 5
Metal Gear 1+2
Metal Gear Solid
Metal Gear Solid 2
Metal Gear Solid 4
Metal Gear Rising Revengeance
Then he will just have to do story before MGS3 with the Boss, and story in between 2 and 4 and the saga will be complete.
Portable Ops should also be made prologue to Rising, that was EVERY Game can be awesome. Metal Gear 1+2, Metal Gear Solid 1, Metal Gear Solid 2, Metal Gear Solid3, Metal Gear Solid 4, Metal Gear Solid 5, Metal Gear Solid Portable Ops Peace Walker, Metal Gear Rising reveangance and then the other two games. That will end series with ten games and all ten AWESOME.
