Have you ever been confused by the weird sequel numbering in movies and videogames? Well, you’re not alone. This guy explains the confusing details of the numbering of movies and videogames. I still don’t understand the whole Street Fighter and Mega Man numbering system. This guy is pretty funny.
Note: Some of the numbering changes in sequels has to with the makers attempting to distance themselves from some of the more terrible movies or videogames. Does the new Rocky film really want to be related in any way to the horrible Rocky V?

One of the worst companies that was responsible was Wisdom Tree, which ripped the game engine from the American version of Super Mario Brothers 2. Who knew people back then just carried sheep and lions above their heads?

I think it's a toss up between BTTF and Alf videogames. I vaguely remember playing Back to the Future. That music is horrid too.
I wonder if they simply released it as Back to the Future and it was actually something else completely.
