GDC is a site for game designers to post their games, in what ever version state they are (alpha, beta, or gold/master), so the people may view and play them in order to give feedback on what they thought about the games and suggestions to game designers on what they can do to improve on them. Posting game designers may also post the concept art and screenshot for their games to get additional feedback on their in-production games and create blog posts to keep users of the site updated on the latest news of game production.

Welcome to GDC, to possibly renamed later. In the coming weeks, this will become a place where game designers and developers can come together to post development blogs about their in-production games, post alpha, beta, or gold versions of their games, show their process, get feedback on their work, and get tips and resources from their fellow game designers/developers.

Check back often to see what's new.
