First let me say that in-app purchases have ruined potentially good games. The developers write their applications with the intent that players will need to keep making more purchases to get ahead. This isnt a game of strategy. Its a game of "My wallet is bigger than yours". The top players all have top VIP levels, meaning they spent a gob of money. Hundreds of dollars in some cases.
Progress initially isnt bad, but as you move up, progress slows because of supposed random possibilities of gain. Example: in one situation, it takes 3meg of rare earth to upgrade a device. Each upgrade is more expensive of course, but on top of that, the likelihood of the upgrade happening decreases so that 3meg if rare earth will cost you between 15 and 50meg. Of course you buy instead of gather. Thats what the developers count on.
I had very few problems actually playing the game. Periodic crashes. That seems to happen with all games. Certainly not as many as some fames Ive seen. If you get attacked, you dont lose everything that youve been accumulating. Much better than many games like this. Ive never lost my game like some people complain about. You can play across multiple devices. I played with an iPad 3 at home and an iPhone 5s away from home.
As long as there are players that are willing to buy there way to the top, developers will continue to produces games like thais that you can always win if you want to spend the dash. But seriously, what fun is the win when you win like that.
Still looking for a good game that depends upon real strategy and brains to win.
