This game would be amazing if you could buy gems w gold. I dont mind a slow grind if I actually get to play the game, but as game currently is if you don't want to pay to win, the grind is watching countless ads..... :( Edit: No problems with the game other than you get to a point where to progress you have to watch ads. (Can only receive a certain number of ship and drone upgrades per day with multiplayer and single player activities) Would be much better if you could trade gold for gems.
