Recently I have found something called the
Experimental Gameplay Project, which is about creating games based on original ideas by a single person in 7 days, based on a common theme. Apparently it has created some great games, and it is well known in the indie game development community (which means that I have seen it in at least two places;) ).
I wonder whether there is any inspiration between this project and our 7DRL Challenge... some things are very similar (equal team limit, equal time limit, focus on experimentation). Apparently they both started in Spring 2005, and I don't see/remember any side admitting to drawing inspiration from the other one.
Maybe it would be a good idea for our next 7DRL Challenge to suggest basing the 7DRLs on the EGP's theme for this month (unless our devs have their own idea which conflicts with their theme, or their theme is incompatible with Roguelikes at all), so we can spam them with Roguelikes (AFAIK anyone can submit a game to EGP).
