That's exactly right! this game is anything but a "free to play facebook app". granted, you can play without spending money, but if you want to succeed in this game you will have to watch commercials, try software and so on, and that means you invest time, effort and sometimes money.

If this game was really free to play, you would have a limited amount of tokens and money every season.
the fact that we had to start our own league with a limited amount of tokens is evidence to that...
