Didn't this game has some sort of pay wall behind free content? Like 'You get to play up until this part, the rest need you to take out your knife, stab your wallet and throw your moolah at the screen' pay wall?

So much fail. No, I don't expect anything from your ability to read.

In case I wasn't clear, I was asking about the history of the game because I just found out about the f2p transition. And it was answered perfectly. Not by you, of course.
