This can be big Pay2Win game. If you forget to shield, you will get raided of your main resources (not everything, tho!). Get ready for a lot of daily grinding. Free to play? Sure, but it will take time... And time... Customer support IS very responsive. Pricing of packs are too high for the real in-game benefits and very bad ratio of bang-for-buck. Still, a very cool game! Playing for 3 years now!!! New content every month!
