If you have a decent interweb connection, check out this game. It features Hulk Hogan, Mr. T and Fat He-Man fighting Bush and his team of RoBeasts. Also, Darth Rumsfeld, who took me a while to beat with that spinning lightsaber of his. You get more characters as you go along, and Screamin' Howard DEAN was obviously my favorite.
It's also pretty informative, if a bit heavy-handed, on exactly why Bush has been such a horrible president, aside from all of that war business. Sent my way by The Jenny, official member of the Nati Crew.
(I really think the Nati Crew deserves its own website. Someone get on that.)
