Art-wise: I do wish there was a bit more variation, but I don't really mind the art medium, so long as it's done pretty well. If it's done badly, I find I dislike it more, the more real it's supposed to look real. I guess it's something uncanny-valley related or my mind filling in the blanks with simpler art or w/e.
That said, I think it's story/scene content that's the biggest point of frustration for me. I find it hard to pin down exactly
what I want, but the vast majority of games ain't it. Single paths in bigger games annoy me if the only thing drawing me in is lesbian content. I like
some lesbian-only games
some of the time (especially when the cute factor's maxing out), but I think I tend to find them a bit slow and vanilla a lot of the time. I do like games that aren't lesbian-exclusive or focused, but the games and stories I've liked best do tend to be lesbian-focused. I'm just struggling to work out what I like and express that in words. Oh well, that's a problem for tomorrow now.
(note: this isn't a rant at anyone here, just me thinking aloud)
Also, top question jogged my memory when I started trying to look up good Honey Select CG games. What's the opinion on M2F TF games, if the main character is a man in a woman's body for the majority of the game? I saw early on that futa was ruled out but gender-bender might be OK. If so, I'm like 99% sure Love Change has "lesbian" routes that aren't just token inclusions, although the game does branch out towards the end and I haven't seen all paths. There is a mid-game switch back for a short while, and I could have mistaken some mandatory dick later on for some optional dick if I'm misremembering something, but I really doubt it - the game was pretty good at giving options the whole way through.
edit: disregard the above, completely blanked on a scene in the middle which is mandatory, don't consider for list. if you're flexi it's got better options than some limited-path games though
And my second tangential whine reminded me of another game:
Bondage College, one of those games that I really liked a lot (until I realised it was abandoned anyway). Played it plenty and I don't think there's a single dude in it. It also cuts off right at the point where I'd say it gets good.
(I guess if combining this and Shield High then I can work out that I like lesbian BDSM relationships and school settings; I feel like there's more to it than that but I can't think of many Lesbian BDSM games, so... it's a lead, at least? also games that get abandoned
