Started in 2001 by game designers Stephen Glenn, Dominic Crapuchettes, and Mike Petty, Protospiel is an annual get-together of amateur and established game designers to test and promote nearly-finished game prototypes.
The atmosphere is casual, yet everyone is serious about their goals and dreams of publishing games.
