When you say "similar to this one" I assume you're talking about the level and quality of writing? It's rare in these kinds of games, which is what makes Power Vacuum stand out. I still enjoy mindless fantasies and "magic cock simulators", but I rarely get attached to their characters because they're typically so one-dimensional. This game's characters, while over-the-top and far-fetched, have a degree of depth and distinctiveness to their personalities that is endearing.
Have you tried Chasing Sunsets? It's got sort-of-incest taboo (it's complicated), fleshed-out characters, great renders, and an overall comfy vibe.
