It's good, not great. Kinda laggy, kinda grindy, though the gameplay was quite good. People are complaining about the ad breaks but they really aren't terribly bad. It's just a tad boring, since practically all it is is grinding for resources over and over. Play it? Maybe. Spend money on it? Eh, I wouldn't recommend it. Even ad free (which is like ~3 dollars for most games) is a whopping 6 dollars. Just remember though, this is my experience with the game, you might have a better or worse time.
