Nobody could ever have fun with one game right? They play, get bored of it, and move on. But with Super Mario Bros, every play through felt like an adventure to me. There were only 8 worlds, but to me it felt like several.
Well, the truth is that there are actually 256 worlds, but it's garbage data, mish-mashes of different levels categorized as a world. But that was just the tip of the iceberg, there were so many other things to do.
Try out different glitches like the Minus World or Small Fire Mario and the endless amount of Game Genie codes all meshed well in the world of Nintendo's creation.
I don't play it too much anymore unless I'm playing a ROM hack or corrupting it, but all I wanted to say was thank you, Mario. You really changed the person I am today.
