Man, I'm so pumped. I've spent the last hour looking at the achievements list for Master Chief Collection while at work, lol.
I might be insane but the idea of working towards all those achievements has me so fucking excited, hahaha. The sheer breadth of achievements has me so irrationally happy... achievements for so many little things, like achievements for getting each skull individually, and then another achievement for getting all skulls. Or achievements for getting each terminal one at a time, and then another achievement for getting all terminals, and so on.
I've never played a Halo before other than Halo 1 Anniversary on 360. So I went ahead and bought the digital version of MCC yesterday. It finished downloading on my console. Via Home Console game sharing it should be finished downloading at my brother's place by the time I finish work too. I really can't wait to start playing through the 5 campaigns in co-op with my brother.
For the beginning, I plan on just doing a normal playthrough of all 5 campaigns with my brother. No worries about achievements, just play through all the campaigns and enjoy the story. That way we should easily be ready for Halo 5's story.
I think it should be a relaxing romp through those achievements. Though I already know I will not even attempt: any LASO achievements and very few par score achievements. Those seem too stressful. And some miscellaneous achievements may be too difficult (i.e. complete The Library on Heroic/Legendary without dying - I could never do that on 360). I'm hoping I can hit 5000 gamerscore out of the 6000, heh.
This last note is more just for me as a reference. I'll need to make sure I don't miss:
Play Halo 4 on the 6th of any month
Play Halo 2 on the 9th of any month
Play Halo 1 on the 15th of any month
Play Halo 3 on the 25th of any month
Play Halo ODST on the 22nd of any month
