I played this game and got into the discord channel too. i would say that without mods its barebones as modes make a lot of gameplay, get atleast emporium, blacked, dredd intimacy, office girls restore, and bar spike, and dont forget wharf too. I am using 100 mods and its still on low side to be honest, but mods enrich this game. Some mods help in feminizing character more, some helps in masculanization. Some add beefy story lines, and so on. So you need them, total size will be around 30 GB or so, so yeah mods are a big thing in this game.
Now on to discord, while most are actually cool to talk with, some old players in the servers are cranky and downright condescending, and its quite difficult for a newbie to get started. But its minority, rest are super cool and supportive, even if some major people in the server are jaded and not newbie friendly, most are very helpful so I would suggest to go in channel if you have some questions but do expect some of pushback if you ask about updates or criticise game and so on.
Personally, with mods this game is solid 9/10 game. And upcoming mods are really good, one is for proper stripper job. Another similar game I would suggest is Clean Slate, that game at base level alone is 9.8/10, its silent nowadays because dev is moving from QSP to twine but it is really a very good game but having more natural progression and corruption than X Change.
And for updates, expect 3-4 or even 2 updates a year. Aphrodite have other projects too and honestly base X Change game just adds overall features and framework for mods, you should look more for mod updates.
