Huh, well, I gave this a try on a whim, and I'd say I'm pleasantly surprised thus far. It's rare for a game to have a protagonist gender option, and while I certainly would prefer the male anyway, the female option got my interest so I went with that first.
And it was pretty nice, all things considered. I'm always a little iffy myself on the Daz-style models, but I just always liked Illusion's stuff in general. Still, none of the characters LOOK bad, so that's good.
Writing-wise, I'd say its solid.
The Training System, I think, will maybe be the first thing to really judge in the long run. I do wish there was a 'back' option after you pick a category, in case you're just checking what's there. It's nice that there's different dialogue for the first time a thing is selected.
However, I worry past that, it might get a bit repetitive, since after that its (understandably) generic. But given it seems it could take, say, 10 times of cunnilingus to go up a level, reading the same thing 9 times... well, repetitive. While having more unique dialogue would be fantastic, it's probably more realistic to just see how the 'leveling' curve goes.
About the only small nitpick I have on the female MC route thus far is in terms of breast size. It might be a Daz-model thing, but her size seems to kind of... vary between sequences. The bit about the peasant dress being tight on the chest, implies to me, a rather large chest, but in the scenes with Valerie she seems a lot more on the small size.
I'm not sure how realistic it might be, but an option of some protagonist customization with that could be nice. But I am unsure how much that might add to the overall workflow. It would be nice to have a busty female protagonist though, but that is just always a personal thing.
I'll have to give male MC a try later, but thought I'd at least give some thoughts on what I saw on the female MC route thus far, as its a rarity in games like this but, thus far, appreciated.
