Once upon a time, I wrote a post about all the things I'd want to change in Traveller if I were to run it again. The other day (... or month), I started to draft a similar post for ACKS, in part in response to the ACKS 2e proposal that was floated on the Patreon. In general, I dislike the direction ACKS seems to be headed; as I said a year and a half ago - "ACKS' continued development seems to be away from its slick, usably-abstracted B/X roots and off into what the forums jokingly call Advanced Adventurer Conqueror King, with more detail and more rules.". The 2e draft reinforces that perception.
I considered digging through the pile of retroclones to find something that better suits my desires, but I find my patience for reading rulebooks has fallen over time, particularly with all the duplication that you tend to see in retroclones. I found myself wishing that retroclones were just published as changelogs, as patchnotes, or in proper version control systems.
And then I remembered caphiend's ACKS SRD on github, and went "what the hell, somebody has to start this." So here we are - a version of the ACKS SRD with a growing selection of our group's conventions, houserules (or proposed houserules), and clarifications integrated into it.
