FAP Nation Review

Filtering by engine is the detail that marks this out. Alongside genre and popularity, the site lets you narrow by the software a game was built in and the platform it runs on.

That sounds technical and is intensely practical. Adult games are overwhelmingly built in a handful of engines, and the engine predicts almost everything a player cares about: whether it runs on your machine, whether saves survive updates, whether it is a visual novel or something with actual mechanics. Genre tags predict none of that.

The catalogue covers games, comics and adult video, with a latest-games feed for tracking the perpetual updates this category runs on.

Downloads are free.

A band of AI and cam services runs across the top navigation, sold rather than built.

Most of what is listed is work in progress by independent developers, distributed here rather than through their own channels — so what you download may be a build that has moved on since.
