I have a XBOX 360 and play it every now and then but the game system our crew uses the most is Nintendo.  Not Super NES, Nintendo DS, or Wii........ I'm talkin bout ol school Nintendo with Duck Hunt, Contra, Super Mario, Excitebike, and the greatest game ever made - Tecmo Super Bowl.  We play this at Gourmet's house on the regular and only have one rule - no one can play with the Raiders b/c Bo Jackson is so freakin fast it's not fair to the other team. Below is a video of a rather intense game between Gourmet and myself.  Parental discretion is advised..... a serious game of Tecmo Super Bowl results in some pretty foul language.
