Heh. as one of the ones who came back simply because it was free, I can say this. it's a heck of a "Free Demo" Got me to resub. And from the Gen Chat, sounded like a bunch of other folks did too. Those that don't, Oh well. Seriously. You don't have to buy the game to get free gameplay that's restricted. You've got no skin in the game at that point. They don't hit people with the banner ads, or interrupt your gameplay with ads. It's a pretty nice game for free.
