Not sure, from personal experience, Anon seems best at the moment.Anon version is the one where the author who did NOT go off the deep end, right?
From my understanding:
1. the original is outdated and updates slow
2. Pedy swapped out some characters, and added malware that messes you up if you try to put them back in
3. Anon took out the malware and put the characters back (seems sane so far) but seems to want to change the English? Some people seem to have issues with his English but it doesn't seem to affect gameplay
4. Popsalot... he added a lot of features, guns, death, factions, diapers and scat, and QoL stuff; it says you can toggle them off but the content toggles aren't fully functional, unfortunately ... lots of features also means tons of bugs. There's good stuff mixed in but it tries to do too much too fast.
