For me it's the original Mario games. My friends used to race over how fast they could beat the first one. I, however, did not care. At all. I owned three Mario games on the NES and SNES and didn't get over halfway in any of them. I didn't like the character, I didn't like the (lack of a) story, I didn't like hitting blocks over and over, the coins, any of it. There were so many better games on the NES. Give me Mega Man any day of the week. I will always believe that the Mario phenomenon is entirely due to the game being included with the system. I have nothing against Nintendo, but I look forward to the day when Mario is in decline so people can discover something different.
