Some people like to collect things, particularly when those things are items which represent something they are passionate about. When it comes to EVE Online, the MMO I play, the playerbase gobbles up official merchandise from CCP whenever it can. Many of the in-game corporations, alliances, and coalitions have also made buttons, armbands, patches, coins, medals, pens, mousepads, mugs, and all manner of other kind of promotional materials for their members. Then there are the individual players who frequently make their talents available to create fabulous artwork, videos, logos, tshirts, posters, paintings, sketches, and more by request.
Welp. Here I am, tentatively throwing my hat into that ring.
