Seriously, Tetris is a very communist game.  First off, the pieces are literally equal: they are all made of four blocks.  They must work together to receive their falling comrades with open arms.  If they don't link arms in rows, they hasten the end of the game and a return to bourgeois oppression.  There's only one catch: who's coordinating all the pieces to work well together?  YOU ARE!  You're the communist dictator.  Without you, those lazy pieces would just fall straight down and ruin everything.  Thus Tetris reveals communism's inherent defects.

    However, in TetrUS, which represents a free-enterprise capitalist democracy, YOU have been elected President!  In this version, the pieces represent a never-ending stream of issues, which must be spun or side-stepped quickly to prevent disaster. If you can't make all the pieces fit together, the public will eventually catch on, ending the game and lowering your approval ratings.  If that happens, press "R" for "Re-elect."
