It's the product of nearly 15 years of work, improvements, and sequels. There's really nothing like it. It's a fighting game, but it's not your run of the mill punch-'em-up. Instead of working off of health, it introduces a system of damage where the more damage you have the further you can be launched. It really adds a fun new side to the genre. It incorporates some platforming too, and what's more, it's a huge Nintendo crossover. You have characters from Super Mario, Pokemon, Legend of Zelda and more battling it out in a game of skill. I couldn't possibly describe the entire game in a single paragraph, but it's definitely one of my favorites. My favorite character is Samus. If you don't have this game, get it! It's incredibly awesome.
