I have yet to start using this API but has anyone used this for a site not based on gaming? I haven't really looked into it too much yet so my question might be stupid, don't destroy me for it. If this api can't be used for this does anyone know a software that has a similar point system that is out there?
You could use it for a site that's not gaming-related, but most stuff you retrieve from it will be gaming related. After all, that's what Giant Bomb is. If you want data on comic books, Comic Vine has an API too. Although based on your last sentence, I'm not sure you understand what the API does. You can't get points from it, nor can you perform any point-related queries.
