Super Smash Bros. 4 3ds and wii u is one of the best fighting games out there in my opinion.  Smash wii u is better then the 3ds version, but the 3ds version is still very good.  I would give the wii u version of Smash 9.7/10 and the 3ds is a 9.3/10.  It has a very large roster, and is very easy to control.  It very easy for beginners and is very fun for advance players.  It doesn't  get boring.  Its game play is very fun and immersive.  It has great online play were you can play with people all across the world, and you can host/join a group that only your friends can play on.  It has very good DLC( downloadable content ) with fighters returning from past games like lucas, mewtwo, and roy; and even as a new fighter ryu from street fighters.
