what you said about the graphics is straight up false

Really, then why not go up to a rock/wall etc in Halo 1 and then in 2. Notice how much more detailed the textures are in the first game, that you can zoom in on the rock etc with your weapon and make out even more intricate detail without things becoming really blurry. Whereas in 2 as soon as you go up to a surface it becomes blurry without zooming in.

Then there' s the bump mapping on the environments being better on the first as well. Again up close in 1 things still look extremely polygonal when they' re not, whilst again 2 just blurs things and breaks the illusion.

Halo 2 looks better in regards to lighting for explosions, and character detail polygon and effects wise, and it also runs smoother. But overall looks noticeably less impressive.

Having said it doesn' t effect the gameplay.
