I was toying with the idea of a Yendor 2 and/or 3 remake, probably starting with the engine. I would make this an open-source project, probably with a desire to make it browser based using HTML5 and WebGL technologies. This is a very, very niche project, but I'm hoping there might be others out there interested in embarking on such a project? Maybe Rodney Smith or anybody at SW Games could help out?
