To be blunt, I never had a whole lot of interest in coming back to Halo 1, but having decided to do so anyways, it holds up surprisingly well! I had a good time with it, you can really see why it was influential. It does start running out of steam after the big flood reveal, but everything that leads up to that and the excellent final setpiece do a lot to make up for it.

I actually think the anniversary visuals are a fun novelty, but obviously the original version is absolutely the way to play. The terminals however feel like a weak afterthought, and do nothing but muddy up a solid story. They might be worth experiencing just to say you did, hell maybe they sparked something for hardcore fans, but I'd say save them for a second playthrough if at all.
