Not totally bad. RNG seems a bit screwed, but I can live with that. But once you up grade your bases to level 4 it takes me over a month to save the 43k gold it takes to upgrade. In my opinion that is entirely to long. I have spent a few dollars but what it would cost to upgrade the bases that I can would cost me hundreds of dollars. Sorry not wealthy can't do it. Right now it's just a grind everyday. Getting bored. Probably won't play past next update.
