Opengress isn't anything yet. Maybe it never will be. Maybe it won't come from here. Hopefully the name changes. The aim is to create a free (libre and gratis) set of components to help build location-based games and experiences. It's not so much about creating a game, and more about creating or documenting algorithms and libraries for use in creating a game.
It's for players and developers, not accountants and shareholders.
Currently there is largely functional intel, remote submission and a review system. Work is slow but ongoing.
