Lame, it seems like you have to buy the game or spend 10 ecoins per minute.

Or am I wrong?

I'll just try it out first with the free 500 ecoins you start out with.

EDIT: You increase the ownership discount after each level of the game you complete but I'm almost out of coins and the discount is not much. I got $0.53 discount after using up like 200 coins.
Also the shooter game is kind of repetitive and is not online/multiplayer.
