Is it the nostalgia? Is it the graphics? Maybe the analyze feature?
I’m excited to see the Flood again and to hear the English version of the Covenant voices, of course it’s nice to see a refurbished game with the chief again too!

I’m really excited to see the graphics- they look amazing!
I’m also really excited just to be able to play the game, though, because I never really got the chance to play Halo:CE.

Nostalgia! Co-op with my younger brother like we used to back in the day.
Primarily, Co-Op over LIVE because I have a huge Legendary run planned, but I am also looking forward to the Library, so I can actually navigate it without dying in frustration.

The fact Halo 1 is back, graphics and Co-Op over live 
The excitement and enthusiasm in the threads is basically me as well.
The updated and insane graphics

Fighting the flood. We haven’t fought them in the last 2 games. Can’t wait for nostalgia too. I am really excited comparing them to the original Halo CE flood. I am most excited for playing the level “Keyes” because I want to see the graphics for when you punch the brain form. Sounds childish but one of the most important parts of the story IMO.
