Of course I could start things off with a thesaurus full of words describing Resident Evil's graphics - but none of them would do the game justice. This game is not only one of the best-looking games available on the GameCube, but I would venture to say it's one of the best-looking games available on any system!
Stepping back from the 3D backgrounds used in Code Veronica, Resident Evil gets back to the true roots of the game. Every rendered background is almost like a mini-movie of details. Moths dart back and forth around dim lights, water ripples and splashes when it's disturbed - even the smallest blades of grass have some movement in them. Of course, you can't forget the requisite flashes and crashes of thunder and lightning. I could go on - but then I'd just be rambling.
Since the rooms are rendered, that means the camera position is fixed - but the angles are so well done that they not only keep the game playable, but keep the creep factor up as well. This does lead to moments where you won't see a zombie on the screen, but such a little thing is forgivable.
Character models are so well done, it's almost too creepy. Actually seeing the expressions on characters faces adds a whole new dimension and immersion to the game. You really begin to think the characters are scared for their lives. Again, I could go on - but it's something that mere words can't describe.
As if the graphics didn't make the game creepy enough, the sound only enhances it. The slow, moaning shuffle of zombies, the clicking of the dog's nails on the floor, and even the haunting piano melody in the background are all present - only now with a much cleaner and creepier sound.
