Hold on to your wallet, not much of anything 'free' about this one. Want to make progress without buying it? Prepare for endless grinding for chump change. First 2 versions were a blast and progress was possible with a little time and effort, not so now. Watch an add? Stand by for spam email, they're making money from those, too. I'm all for putting a little money in for some fun, but not at this level. Game is fun, don't get me wrong, but I'm tiring of it quickly. My wallet is staying closed
