Well I can only speak for why I've followed the development of this here, since I never supported this project money wise. Its one of the more promising sandboxes out here, unlike something like accidental woman that is flawed from the start and basic things are still either buggy or just very barebones (that impregnation code though, we need to spend 10 updates to make sure its realistic) the sex, npc interactions, pregnancy system are all very nice BASES for a good game here.
If this game just focused on the sandbox more, made like way more sex fluff text, improved on relationships with npcs instead of adding every single furry species someone on tumblr came up with then it could've been a really great game. Every now and then I will replay this one, play for a bit, enjoy the parts that work well, and then dump it.
It still has a chance to be great, is it very likely? Probably not, but its still worth playing like once a year or two I think when maybe there is enough content to enjoy it for like a weekend. Sex systems in sandbox games usually suck ass completely (again look at AW, god that one is fucking awful) this one has good base for it at least, sadly it doesn't have nearly enough text relegated to it to not get stale after a while though and not enough stuff like that imp equipping you with a plug after sex to make sure you get pregnant, imagine way more stuff like this, there were signs of greatness and it made people hopeful I guess. The modding doesn't really have anything interesting to add, maybe because I don't want my little pony race mods, maybe I'm just not a target audience for this game, someone who is REALLY into furry might be happy with specific anatomic kinks being mentioned or used.
