I was under the impression Atlas was trying to make persona 4 like the opposite of persona 3. Since P3's main color aesthetic was dark gloomy blue, they made P4's a bright happy yellow. And it was awesome. I can't think of a lot games as colorful as P4The Wykydtron said:Definitely Persona 4. It's all yellow and cool and shit. I have no idea how they thought it up but bright (but not too bright) yellow is the main aesthetic of the game. It's totally awesome.
On topic, I've already had persona 4 and fallout 3 ninja'd from me so I'd have to say super smash brothers melee. That iconic opening line from the narrator and the epic music and the layout of the menu were perfect. Also Metro 2033 if only because the music makes you feel like you're about to start an awesome adventure
