Pretty good list, with some caveats.
Some of the cross-game ones are really grindy in nature, but given how much I'll be playing this I'm sure it won't take long at all. There's only a few multiplayer achievements, and they're all of the "Play/Win X games" type, thus fitting into the previous category. I like how there's ones for completing each individual level with par score and for completing them in under par time. Those LASO ones are going to be a bitch to beat, though. There could have been maybe a bit more variety, and there really needed to be one for beating AotCR entirely on foot, but overall it's a good list, doubly so since all those old MP achievements from Halo 3 & 4 aren't there. Damn, those were terrible.
Overall, it's a solid list. It could've been a bit better, but it could've been a lot worse. Bungie made some really stupid achievements in the past. And even some of the ones 343I made for Halo 4 weren't so great, either. This list is thankfully devoid of anything truly asinine.
