Those might have been actual renders, not cards.
I would say this game, there is no telling when the, now extremely dated, Honey Select 1 community will cease activity, but this one should be active for a long time yet given how long its predecessor went. The thing you will have to keep in mind is that NONE of these games you listed work together, so whatever you create is stuck in the game you use except with Honey Select 2 being able to port back to AI Shoujo.
You mean a mod that simulates pregnancy by changing the shape of the girl the way you want? That exists. It's in the repack already.
I do believe he means like the new port of the Koikatsu pregnancy mod, which only exists in AI Shoujo with the original being in Koikatsu. The difference is it is an actual mechanic with the Koikatsu mod that got ported. I don't remember seeing an announcement of a port for it to HS2.
It depends on if you have the Sideloader Modpack. With it, somewhere in the 90GB range, without is somewhere in the 30GB to 50GB range. The Sideloader Modpack is ONLY for the studio, so if you don't use the studio, you don't need the modpack.
You can port over your entire UserData folder, so yes, you can bring the saves AND your character, scene, and coordinate (clothing) cards.
Those files need to go into the Mods folder, there should be a bunch of folders with the term Sideloader.
