The graphics are fantastic too. I saw a lot of people poo-pooing it on release, but I think it's gorgeous. The lighting especially puts it in another league, it makes the game so much more pleasurable to play. In previous playthroughs (even when it originally came out on PC when I first played it) I choked down the bad lighting and ugly environments, but now it's a pleasure to play. Well done 343.
One issue I'm having is that the game will forget my controller settings when I start playing it which is weird, has anyone else come across this?
The game really is beautiful, especially the lighting. There are some valid complaints about the new graphics altering the mood of some of the darker areas, but it cannot be said that it doesn't look great regardless.
I've never had any issues with the controls, but I have everything set to the default except for the Recon button layout.
