Fantastic game, I've neevr been so addicted and involved to a game. Like all games, it has its good and bad people of the game ocmmunity, but the good part is always very helpful. A Very competitive game so watch out for that.
Some people i know seem to be too hard on it. But one thing you have to consider is, you cant see it or expect it to be like smash bros.
Sure it's kinda the same concept, but most people that i know that expect it to be like smash end up hating it. That's obvious because, well, it's NOT smash. Overall, my fav game on steam, and its free too.

The one con is that you have to have pretty stable connection, lag on this game is scary, it'll make you lose instantly.
