Very polished. Looks beautiful. The controls work very well and the mechanics are functional. However at higher levels it feels like a cash grab. So frustrating not being able to do anything because I feel like I'm being steered towards purhases. Even if you were the buy into the game an amount of stuff equivalent to a full priced retail game, you'd just be in the same situation soon enough. If it was worth it I'd buy it. Tellingly, rebalanced this might be a 5 star game.
