Great game however it is heavy grind. You max level quick but grind heavy from that point on. UPDATE: After a few years of playing, unless you are dishing out a lot money for all the new units you will not stand a chance anymore in pvp. It was fun but the game is too much of a money grind. Some people have done well just grinding but it can take months to get anywhere. And as soon as a new units come out all the ones you worked on are now useless. So your choice to try it or not but I downgrade
