Super Mario Bros. minus world:disk system version
Somehow my mind was rather mesmerized by this little film.
After I saw this little film I tried to go to minus world myself, but the 2 versions of this game I have don't include this funky little world. Maybe someday I'll will have a minus world adventure of my own. Also I read online that, the Nintendo Wii version of Super Mario Brothers has the same minus world as shown above.
PS: This post is slightly lame. Sorry, I have been working on some recordings for the most part so this lame post is highly justified.
