GOOD graphic, GOOD concept. NOT much content (only 3 modes so far). PAY TO WIN, NO STRATEGY, top up your cash, upgrade your legendary armies, you win. price is EXPENSIVE, buy the cheapest package ($5), and what you get can hardly purchase anything of worth. BARELY IDLE since you have to keep your phone on. VERY HARD to get rare units, heroes, artifact without purchase. VERY GRINDY, 8 hours of leaving my phone up only get me enough money to advance 4-5 run stage. MANY USELESS troops.
