I always enjoy reading about the process game designers go through when creating their games, and how the games evolve throughout the process.
For anyone interested in the process I went through for my first published game, coming out through Pegasus Spiele this month, see my newly-created blog for our Berlin designer's group:

My hope is to include future Prototype2Publisher pieces from other designers in the group as well.
