UPDATE: I first rated this game at 2 stars, noting that the game freezes and crashes regularly. ucool responded by asking that I send details on the problems. I sent a long email with lots of details. Tech support responded that the problems are caused by 'network fluctuations.' It seems like they don't want to acknowledge the problems exist. There is no guarantee that they will ever try to fix the problems. EDIT: Please see tickets 793531 and 825055. Many details there.
