Danc at Lost Garden wrote about GameInnovation.org, arguing that we need better, standardized language in order to discuss game design. If everyone has a different definition for “challenge” or “reward”, then you can’t hope to have a meaningful conversation with other game developers.
The goal of the GIDb is to classify and record every innovation in the entire history of computer and videogames.
The Game Innovation Database is in a wiki format, which means that anyone can contribute. I especially like the Challenge Page, which asks questions such as “What was the first digital RPG (role-playing game)?” and “What was the first game with autofire? “. You can browse by game or by innovation, and of course you can edit something if you think an article is lacking, missing, or just plain wrong.
