And there you have it folks - Lyra's List #2. I strongly urge everyone to take a look at these, especially programmers/artists/etc. looking for a project. They're very well made GDDs and very interesting concepts. Also, if you have an idea for a game, and are looking for people to make it a reality, submit to Lyra's List. And not every game has to be a long term project, either - short term arcade style games can be really fun as well.
