3 stars: 2 stars for graphics. 1 for gameplay. It definitive pay to play game. It's to expensive, to fast. If there was a mode in which you didn't have to pay to play a match. And ranked in a different way. It'd climb up to 4 stars. That said, upgrades of course cost in-game coin. Which goes up ridiculously high fast! With minor increments to said upgrades.
3 stars: Controls too sensitive. Characters should not be able to run circles around the ball to hit. It would nice to be matched up with players of comparable skill level instead of being paired up against he player that is a 1000 times better. It would be nice to know what the tour cap attributes are. It is also a pain in the butt trying to figure out best combination of equipment/attribute to match with each character.
3 stars: This game used to be fun until the last update. Having certain things cap out makes it no fun because you can't go back to other levels without being affected. On top of that, its impossible now to win no matter how good your person is. How some people are capped out on lower levels, and others aren't, I don't understand. But it is what it is I suppose.
4 stars: Lots of negative feedback below but I bet they are all playing the game still as its addictive. I find it realistic, allows you to tailor your player to a style you like and compete with people from all over the world. I personally love it but agree it isn't perfect but very hard to make a game played on your phone perfect!
