Resident Evil 4 is one of the most highly regarded games. Ever. On the PS2, it's rated as #3 of all time, and actually scores well above the other two games (Tony Hawk 3 and GTA III, if you're curious) when you average in user reviews. It's certainly the high-water mark for anything with the name Resident Evil on it. (Including the movies. No, especially the movies.) People still talk about the characters and the gameplay is still fondly remembered. People still talk about key moments in the game, like the moment when the chainsaw guy shows up. The visuals still hold up today and every time a new Resident Evil game comes out it winds up getting measured using the RE4 yardstick.
