I have payed hundreds of € on both Planetside 2 and world of tank, on EVE i have spent thousands. And i have played many other F2P games there i have spent more then a normal AAA game cost. If i enjoy if it i don't mind at all to pay for it, but if they try to force me to pay they can just forget about it.
I think Nordeus is doing it wrong, real F2P games do alot better then Pay 2 win or pay 2 play games
