Games like Fiesta, Flyff, and 2 moons are called Micro games. It's free to play but a cash shop is there to fund for the game. The only other major type of F2P game doesn't rely on cash shops at all. They rely on advertising within the game. If you have ever played a game like that you would agree having a Cash shop is better. The constant advertisments are quite annoying.
Micro games tend to attract a lot more people and do much better off than other games. As for how Outspark has money it's exactly what Blaaaah had stated, the company already has enough money to probably be funded for atleast a year on its own.
Cash shop kiddies will probably be the best off out of everyone, and pretty much change the economy of the game as soon as the shop is realised. Loads of people are gonna be pissed but over all if you enjoy the game now than you'll be fine later.
Lucky me I can't wait for the shop to come out because I've always been a cash shop whore
