I chose mine because it was a good design and it was for low points. I hardly ever see anyone who has the same as mine. I think it also kind of shows I'm not some nerd who stays up on AG all night spamming game comments and rating games that I haven't played for points.
I use this because I *think* I am the only one around the site that use it and it is quite awesome. And I think it is a better discussion for the General Armatar Discussion Thread instead of creating more armatar thread.
I like using armatars that nobody uses. I used to use the black skull for exactly that reason, but then I noticed it got a bit more popular...
I use the shark because no one uses it, it's in the highest armatar set, and it shows that I'm some nerd who stays up on AG all night spamming game comments and rating games that I haven't played for points.
