Rimworld has a pretty interesting modding scene.

I know Skyrim has an extensive lewd modding scene as well, but I haven't really messed with it

Weirdly, I really like mods in already NSFW games:

• Strive4Power and it's sequel/remake, Strive Conquest have mods that experiment with the gameplay quite a bit.
• I played around with writing mods for Portals of Phereon for a bit to try out some changes to the game to better fit my interests.

I get the concern with mods being complicated to install, depending on the game & it's engine, it can be difficult to keep compatibility with either new versions if the game, or with other mods.

I gave all the dragons and beasts dongs, vaginas, and cloacae in Monster Hunter: World!

If there's options I like to give the female characters large breasts, just cause I like that and no game is willing to give me that and not be porn.

I hate when people tell me to "just watch porn". I don't want porn. I just wanna play a game as a cool or powerful woman who doesn't just serve as a love interest or any other such insipid purpose, who has agency and does awesome things… but just happens to be gorgeous.

I played Witcher 3 a lot during COVID lockdown, and used a mod (from Nexusmods, I think) to change all the paintings you see to Yennefer or Ciri having sex.

Not the first spicy mod I've used, and unlikely to be the last.

No, I have porn for that. Getting horny while playing a game is awkward.

The wife is into it, though. She has several sex mods for The Sims and plays a lot of Hentai RPGs.

CK3's lewd mods added a lot of lewd events and mechanics that made Seduction path a bit better.

I have also modded RimWorld and Sims 3 and 4 before.

The lewd games I played were lewd from the start, no mods required.

Nothing currently. I enjoyed lewd modding Skyrim VR and The Sims 3 and 4 the most.

Dragon's Dogma 2 most recently, but I DNF'd I think the game is pretty bad.
