The "Latest Updates" tab is a really good way to search for games. By fiddling with the filters on the right side, you can change the sort order to get the potentially-best stuff up top, choose the tags you really want, filter out the tags you really don't want, and even choose "Prefix: Status -> Completed" to only get finished games. Even simply sorting by "Likes" puts a lot of 3d VNs at the top.
I haven't played either of Caribdis's games, but if you're looking to expand your base with some games which are nothing like those (neither VNs nor SFM), some of my favorites are:
* Wait, I should probably first warn you that I tend to prefer a bit more game in my porn games and as someone who doesn't mind bestiality I don't know where people who don't like it draw the line. Do monsters count? What about Pocket Monsters? Aliens? Aliens from the film franchise
Alien? Giant bugs? I... I'll throw some warnings where appropriate.
Aurelia - An easy recommend, particularly if you like games where the women aren't restricted to one body type. There are also two (2!) shortstacks. Despite this being the strongest recommendation, you might want to hold off for a bit since a new update got released but hasn't been leaked here yet (we might have to wait a few weeks for the public release).
Town of Magic - a possession-based game. I'm not deep into the possession kink, but I this handles it in a way I quite like. Sex is mostly monsters and humanoid monsters.
Knight of Erin - Erin's thicc. I was a fan of the anime going in though.
Alien Quest Eve - It's a solid metroidvania. This is where the aliens are.
Imouto Life Monochrome - It's a SLG (simulated life game) and I think it's one of the best. The sequel is probably also quite good, though I've only played the demo until now. As the title suggests: it's an incest game, but of a notably different texture than is common in the incest VNs.
Jumble Strikers - Surprisingly robust consequences for getting raped including the pregnancy mechanics. Sex is entirely avoidable though. Bugs and monsters here.
Pokemon Ecchi Version - Its a good, nonlinear pokemon game which incorporates the porn elements well. The latest version could be a bit buggy though.
Summer ~Life in the Countryside~ - These kinds of games typically don't have a lot of meat on them, but Hazuki's got a lot of meat on her.
Horny Bunny Hana - for additional plump. "Monster" is in the tags, but I don't recall any sex with monsters.
