SHilbert and I are working on an entry for 4e5. The purpose of it is to make fun of most of the rules, but it's actually ending up quite a nice game.
I'm keeping some details for now until we release a demo. It's somewhat H-game style, without the AO scenes.
I made a custom file system and a scripting engine for making these sort of games, and it's coming along pretty quickly. I'll so more tech updates soon.
