Level#Tag, very similar to the Rep#Tag but based off games held in ones library.
http://www.gog.com/wishlist/site/leveltag_prestige_based_off_the_amount_of_games_a_person_owns It was suggested that I post this here.
As people know many retailers, both online and off, have various customer rewards systems. This may include a free coffee on every 10th purchase, free batteries with any Adult toy purchase over $100, or even a point system Like Steam has. Currently people are recognised and rewarded for their tireless efforts helping people in the forums, for this they have a Rep#Tag which can increase. I'm suggesting something similar, but based on the amount of games one has in their library. Like it or hate it, purchasing of games provides revenue for GoG allowing them to scout out more old games or providing wages to make improvements to the forums. Every person has a different method of supporting the company they love, it's important recognition is given where recognition is due.
