Super Smash Bros is a well designed game for all kids and adults. Although, it is mostly based on multiplayer fighting and has almost no story whatsoever. There have been people on the internet that have given there own story though. In my opinion, the reason Super Smash Bros is so popular is because of all the characters you have. It is not like you have all these scary big muscular dudes from Mortal Kombat, but instead have all the most popular characters from other legendary games. Like Mario, Link, Kirby. I think Shigeru Miyamoto was quite clever in putting these characters in, because it will sell more to kids and adults. Unlike Mortal Kombat, Super Smash Bros special moves are very UN-complex. Press UP-B for one special attack and DOWN-B for another! Super Smash Bros, overall is a very good game that I would recommend for any hard core gamer.
