Video Comparison : Metal Gear Solid 3DS vs. PS2

[HappySqurriel]

The PS2 version appears to be more crisp and have better colours (the 3DS version may improve upon these things when played in 3D IRL), but the 3DS version appears to have more polygonal detail and better animation (as seen by the clothing animations at 0:30 and the trees at 0:50).
