According to my most recent Excel list I own 1681 game magazines. This is out of date, though, and I think there are a couple hundred or so issues I haven't put into the list. Some of it's in a bookshelf, but most of it is unfortunately in closet storage due to lack of space.
For a look at some of the neater stuff in my collection, check out these entries in my weblog:
