why is madden 2006 rare.
Only the PS2 version is rare. It's because that's the season that EA started making Madden for the next-gen Xbox 360 and was the last year they put effort into the PS2 game, so it appeals to PS2 purists. Plus it has Donovan McNabb AFTER he puked in the huddle and lost the Super Bowl, so it arguably breaks the Madden Curse since it happened after. If you can find these out there anywhere, snatch em up and list them or try to trade them for other rares like Ikaruga for GC or Crash Bandicoot for PS1.
