I was, for a while, very fond of a card game called "Anachronism". It was put out by the History Channel and the idea was that you would pit different warriors and legends from different times against eachother. Unfortunately, the game had the very strange mechcanical flaw that often times actual people who actualy accomplished things were given realistic abilities and stats, and so, did not kick as much ass as people who there were little more than legends about. So the Greeks and Japanese would often end up losing to some guy with a stick because his tribal legend says he's like a demon bear or something. A demon bear with a sharpend stick and no roads or drinking water.
Anyway, as big fucking geeks are often want to do, I decorated my card box with art. I drew a samurai fighting a viking, a really cool sword and a monkey versus a robot, but the crowning glory was this...

A dimetrodon versus a soviet tank. o_o
Inspired by some weird as fuck old collectors cards about dinosaurs raping and eathing everything.
