Quick anecdote, my earliest memories that I can remember is of me playing the Mario Bros. trilogy on the NES.
The music disc also contains several of the well known sound effects from the series such as sound cues for the mushroom power up or getting a 1-up.
Now for a dirty secret, I play lots of video games, I buy lots of video games and I have finished lots of video games in my life.
However, while I played every single Mario game I never finished the originals on the NES. In fact I only ever finished Super Mario 64.
There is also a timeline of the Mario games, each entry contains interesting tidbits by the people responsible for creating the game.
It's a little bit early but I have a new year's resolution already. To finish all of the NES Mario games without the use of any warps. Go through each level and clear every stage and every world.
