Beat the first two Halo games again and enjoy and appreciate them now so much more than I did before. Might play through the first one again this year on Heroic.
I just played the first two for the first time this year. I actually liked the second one's campaign a lot more than the first game's. The first one was fun and had an interesting story, but some of the levels were just huge repeating areas, that were really boring and tedious. The Library pops to mind.
I liked the fact that you played as the Arbiter in the second one too.
My main complaints with the second game's campaign is how much more boxed in the levels feel in comparison. Sure, you visit more areas, but the first has a very good lonesome and depressing setting with a heavy emphasis on exploring and the music that only helps push that. These are some major reasons why Ecco 1 is my favorite game. The Halo 2 feels more like any other action game to me, and I do not like most of the weapons, plus all of them that you can dual wield feel extremely useless to me, and when you use them you cannot use the grenades. Also I hated how in the second game there were sections you absolutely needed to use vehicles, in the first it was optional and would usually change the AI up in interesting ways.
The Arbiter is such an awesome character though, easily my favorite character from the series.
Other than that, I think the multiplayer is way better in Halo 2. The first game has a lot of great fun to it and great modes, but I think the second mostly expands on the best parts.
I am going to hold off on playing Halo 3 for right now, because I let my cousin borrow it for a bit. Thinking about giving Burning Rangers another go and writing a review for it on my site.
