Crap

Constantly bombarded by garbage videos is a annoying. They are desperate to make money from the is game which makes it annoying.
Free to play is just not a great model.
By the time I have to wait for an upgrade to be completed Ive already found another more interesting game to play. Why would I come back and play this mediocre game?
Good luck.
