You guys are over dramatic honestly... if it doesn't happen in this update it will be the next one, at least for some. Maybe it's just me but i do prefer games that build up anticipation and hype for this kind of thing (and it will be better in the longrun for the game). And the side girls are great. Saying they would be disappointing is BS imo.
Also: "Stagnate in terms of content" what does that even mean? It has no sens. Play the game, it doesn't feel stagnating to me at all. The dev time have nothing to do with the game content itself. The game doesn't have hours and hours of playtime where nothing happen and no relationship or story progress.
As for the animations from what they are telling us they will now have a rig solely dedicated to that so we can expect the futur updates to have (much) more going forward.
I agree that anticipation is a good thing. I've never been a fan of throwing all the girls at the MC right away, but we're talking about OVER three and a half years here, and with some of the LIs, you haven't even seen a bare chest. If such a slow pace suits you, that's your call, but opinions on that differ, and I'm different from you. You spend a relatively long time in an AVN with the characters, and after a certain point, you want to have SOME form of reward, but as I've said several times before, I think the AVN's day/night cycle takes away a lot of leeway because, realistically, a massive amount can't happen in half a day. I like the interactions between the MC and the girls, but I've never been a fan of slow-burn, and I have that feeling very strongly here.
I'm happy for you if you're completely satisfied with the pacing as it is, but after a certain amount of time, I just have different expectations for an AVN. We're still talking about an erotica genre here, and Summer Heat is often stingy with that. This still doesn't mean that I need 20 orgies from the get-go, but in my opinion, the buildup is EXTREMELY slow and cautious. And as I said, the update cycles are getting longer and longer, and many people (not just me) found the last update very disappointing. If you create some of the most beautiful character models and renders, you should eventually make more use of certain scenes. Because so far, teasing is the only thing that has happened in over three and a half years.
