Harem in Another World 1.05 (English, Russian, Portuguese)

Harem In Another World is basically what happens when someone takes the classic isekai setup and cranks the adult content to eleven. You play as a regular guy who gets transported to a fantasy world and has to find his missing friends while building relationships with various supernatural characters.

The game gives you two main paths to focus on. You can either go the hero route and try to save the world from some big evil threat, or just forget all that and focus on building up your castle with a collection of romantic partners. There’s decent variety in the characters you meet, from ghosts to goblins to giants, each with their own unlock requirements.

Combat is pretty standard RPG fare, but the minigames are actually fun and help break up the grinding. The outfit system adds some customization for your party members. Fair warning though, this one is definitely not safe for work.
