Mad respect for this post. I haven't seen most of these engines. I personally use Renpy a lot. I also have used OHRRPGCE for making RPG games in the past, its run by a small dedicated team and mostly just one guy for over twenty years now. The creator one Bob The Hamster I belive is his itch name, is still posting and publishing their own games using the engine on itch to this day too.
I am also kinda devastated about gamejolt. I knew porn wasn't allowed, nor nudity. Yet I hadn't considered that most of my games/stories would probably still not be allowed there as they usually boil down to 'two hot women kiss, find out their related, continue kissing and then drama happens but kissing some more is the answer'. Hmm, may need alternative gamesites to host on too, but that's a future concern for now.
