Hiku said: They showed quite a bit of gameplay that was not possible in the original, so it's definitely been enhanced to be more in line with MGSV's combat and movement. Probably more advanced than that even. As for why they chose to start with MGS3, I believe they go over that in this interview with David Hayter. |
I honestly wouldn't be surprised if Konami ends up remaking the entire mainline series. Similar to what Capcom is doing with Resident Evil. Canonically, MGS3 is the first game in the series, so to Konami it would make the most sense to start there and canonically, the second mainline entry would be MGS1. Which a remake has been heavily rumored to be in development for some time now.

Unless Konami decides to remaster both MGS5 games after Snake Eater lol, which I really don't think would be necessary anyway. The games still look fantastic even by todays standards!
