RE4 is the best game I've ever played. The pacing never lets up, the tension, the best boss in a game ever, the enemy variety rotation is perfect, the scenarios are diverse, the environments, the atmosphere, the controls are great, it has mimicked time and time and again and no one has managed to surpass it. RE4 stomps on classic RE's testicles and turns them into crushed walnuts. The only Resident Evil nearly close to 4 is 2 and even that is a lightweight.
I used to think the village was the best but it really isn't. Lab > castle > village. Regenerators are amazing.
