A feature on Steam that, essentially, shows how much of a video game enthusiast you are based on how many hours you spend playing video games each week. The system isn't perfect, as it doesn't include time spent playing games on consoles, handhelds and computer games not linked to Steam (though, all PC games can be linked to Steam even if they're not hosted on it). 0 means less than an hour a week and 10 means more than 35 hours a week. Though not perfect, it is an interesting way of dividing out people who only play games casually and people who regard games as a serious hobby.
I have a Steam Rating of 2, I only play games occasionally as a time waster
I have a Steam Rating of 9, I love games and really appreciate them.
