Where did you get all the information for the databases?
There's not a simple answer for that, but some of the ways we gathered all this info include: too many years collecting and playing too many video games, looking at the games themselves, collaboration with other web sites, list donations from fellow collectors and gamers, pooling information together from the staff, submissions from our members, scouring the web (and then confirming any information with primary sources), jotting down information from games in second hand stores, searching eBay China and Yahoo Auctions Japan, scanning our games, playing our games, etc., etc., etc. Another important thing is that our staff is not all concentrated in one part of a country or the world. We have staff members all over the U.S., in Canada, and in Europe. We're working on gaining contacts in Japan. There are other ways too. Mostly, it all boils down to a dedicated group of people spending way too much time researching, playing, and collecting video games.
