Glitches..delays..the app causes system to malfunction alot..basically takes over..have to reboot and clean about every 10 minutes...and did I mention costly to upgrade and compete..and play..just like a new car payment every week..is it worth it??? There are just too many frustrating and negative things about this game that take the fun out of playing..did I mention that it gets costly, better to consider a 50k investment that has some real value than this artificially created wasteland...
