Awesome Strategy Game…Definately get the add-on

Love this game. The only issue is when apple puts out a new Operating System. I would highly recommend getting the add on for this as it enhances the fun. For those that already have it and found it crashing since the upgrade to El Capitan I guess there is some issue with Game Center. For me I had to log out of game center to get it to load and work. Otherwise, there seems to be no issue. As for this game being repayable…YES. Once you unlock second wave you can customize the game to make it a bit more difficult, fun and definately frustrating at times. As we all know…the computer cheats.
