Fenoxo

Fenoxo is a legendary name in text-based adult games, the studio behind cult favorites Corruption of Champions and Trials in Tainted Space. These are deep, sprawling text RPGs with genuinely extensive writing, branching choices and transformation systems that have kept dedicated communities engaged for years. If you value writing, systems and imagination over graphics, this is a high point of the genre — the games are famously content-rich and largely free to play. The obvious catch is that it is all text with minimal visuals, which is a dealbreaker for players who want art, and the interfaces are functional rather than slick. But for deep, writing-driven adult games, Fenoxo is a genre landmark.
