Do you have an addictive personality? Can't quit smoking or drinking, find yourself spending cash you shouldn't be on gambling, unhealthily over eat, or just generally find yourself getting fixated on things, so much so that you simply can't stop yourself from thinking about them?
If so, DO NOT PLAY THIS GAME. It is built entirely around time sinks and a irregular drip feeding of rewards to get people hooked on it to the point where people are spending hundreds of hours just grinding away to get a slightly better version of an item they already have, just to be able to do more grinding.
It is fun, it's got great gameplay and lovely art design, inspite of the total lack of real story or acknowledgement of progression in such games in the industry at large, to the point where I could believe it were made by Nintendo's evil twin frankly, but it is one of the most cynically designed, personality flaw exploiting games I have ever seen. It's almost as bad as stuff like Dungeon Master Mobile for it's utter contempt for your free time and wallet.
If you're the kind of person that can sink a good 40 hours in over a few months, get up to level 28+, try everything the game has to offer at least once, and then still go 'yeah, that was fun, time to move on', and just walk away, go for it. It's bloody fun, and you'll likely just regret that it wasn't better but have fond memories.
If not, if you start getting obsessed with the grind, and playing the same levels over, and over, and over just in the vague hope random luck will give you a slightly better pair of trousers, then take it back and get Diablo 3 or something instead. At least then you'd be addicted to something that respects you.
