Doing a complete rerun from the beginning since my saves were fouled up by the RenPy switch over and, since I couldn't use the normal skip (I'd have to skip unseen text since the persistent didn't register that I'd actually played through Chapter 6), I decided to just replay as normal - see some of the old jokes again, catch some references I may have missed before, and also unlock the two achievements I somehow missed before.
As of the end of Chapter three, following the written Walkthrough in the OP, and choosing all 4 of the items SanchoMod said I had to choose,
I still didn't get Achievement #75 - Rocketman. There's either a glitch or there's some missing condition.
Any ideas? Anyone know what might be missing, since I met each of the following in accordance with the walkthrough and Sancho's prompts:
Anyway - your thoughts would be appreciated. I just had one more idea, but I'm still doubtful.
EDIT: Nevermind - got it. It's a little more complex than what is shown. You have to
not cooperate with Jaye at all so that you never get to the "apology" scene, and also be a bit of a dick to Mal. The "achievement" is for
missing every missable scene - completely against what normal game play would be for the overwhelming majority of people because
even if you were playing a "be a dick to Jaye" route, it's probably because you'd be favoring the hell out of Mal.¯\_(ツ)_/¯
