PS.: And a tip for everyone. I've sold, for 3 months, 1 copy of my game, for $4. It appears, MP is everything, when it comes to PC games. The market is flooded with SP and FREE MP games, so its very hard to make anything for a living.
I will try the Free-to-Play (in app payments) business model next...
probably this is the reason why other engines have a facebook and paypal integration...
