This is an extremely fast-paced game that I have had hundreds of hours of fun playing with my friends. It's incredibly fun, well-designed, the graphics are superb, and the card & character designs are really-well thought out. The cards are (mostly) balanced, as well as the characters, so there's not one weapon or card that's extremely OP or unbalanced compared to the others. You can play with anyone across the world, from East Asia to Europe, and Africa to the United States. You can also play with your console friends, as they now sell this game.
HOWEVER, despite all the good things I've said, the game is extremely inactive right now, with less than a dozen people currently in-que online at any given time. This is mostly due to the fact that this game hasn't received an update (discounting crossplay to consoles) in nearly THREE YEARS. Unless you have a group of friends you can play with, good luck leveling up or actually progressing through the game. There's also a bunch of "seasoned veterans" who've been playing the game for hundreds to thousands of hours, so even if you DO go online, be prepared to get steamrolled.
The game's progression system also needs work; Friends V.S Friends doesn't really give you any reason to prestige or continue playing except to get these ALT skins for the characters (most of them don't even look that cool and are just terrible overall)
If you do want to play online though, the best places to look are the Europe and American servers during evenings and nights.
If the devs would actually UPDATE this game, it would draw more people close to it. I can't even imagine the potential this game has if it would just be UPDATED.

Pretty flipping fun would not refund this game

Out of my Teague.
