So IGDB has a big set of what they call “External Games” that basically maps an IGDB game to an external service. One of those external services is Giant Bomb, although I don’t think it’s advertised really. They have about 73,000 Giant Bomb to IGDB mappings. Behind the scenes I added an IGDB ID field to our database, and then started populating what I could using their mappings. There’s about 21,000 games that I don’t have a mapping for currently, and there were almost 1,000 duplicates where they had an IGDB game mapped to multiple GB games. I’m going to need some help with this when I can figure out a good way to surface this information 
I’m pretty excited though. I like their API for the most part. I’m sure we’re going to have issues with obscure games, but hopefully we can give back to their dataset with all of our obscure game info once we get going.
