Fantastic game. Back when RE4 was released it was probably one of my favorite game and I considered it to be the best RE game of all time. Now that Resident Evil 4 Remake is a thing, it yet again became one of my favorite game and I considered it to be the best RE game of all time.
I am amazed how they successfully remade the game mostly the same as the original, while also redesigning some levels to be better, modernized the controls, and delivered the most definitive experience you can get for RE4.
The core design of the game remain unchanged, but the implementation makes it very fresh and new even for players who have played RE4 probably for dozens of hours. The AI are also definitely improved. One of the most annoying mechanic from the original RE4 has been revamped and now it is not an annoyance anymore (if you know, you know, and I don't want to spoil it for anyone who hasn't played the game yet).
Modernized controls makes Leon to be more versatile, not anymore a tower defense character when you have to aim and shoot, while also adding new challenges and dynamics because as Leon improves, so do the enemies.
The gameplay feels satisfying. Guns feel very punchy and heavy. Enemies are unrelenting. It proves to be a great experience and it adds learning curve for every players who play the game.
RE4 Remake is a masterful blend of survival action horror game, and probably one of, if not, the best Resident Evil game to date.
