This feels weird to say, because I said Fatal Frame 2 Remake felt bad because it felt too similar to the original. MGS Delta feels great because of how much it feels just like the original, with just a new coat of paint on it.
Although the best part of Delta, is that this game now has keyboard and mouse controls. AND they're really good mouse and keyboard controls. The ability to have such good controls though, trivializes an already very easy game. Boss Fights were just aim and click and you win. Pretty damn sick actually.
Good game though, I very much enjoyed it. I hope they do something like it for the other games
