Very solid shooting mechanics and impressive AI that aged really well. I think that around the mid point of the game the campaign starts to drag a lot and the missions map design and enemy encounters become repetitions of themselves. On top of that the interiors are not very varied and you get the feeling that you are running around the same stuff over and over again.

I dont have any emotional attachment with the original, but it is very clear that 343 took some weird liberties with the art style, lightning and graphics in this remaster that become very obvious specially with the option to switch original vs remake with a press of a button (which I think is a very weird option, maybe they weren't very confindent with the changes?).

Don't really care about the story, I think its serviceable for the power fantasy action hero sci fi FPS. Don't enjoy much the traditional cinematic narrative. And the soundtrack is excelent.
