Supercell size

So I was reading an article on Finnish game developers and it was pretty interesting. Don't have the link but I'm sure I could find it again if I really wanted to. Anyways, there were some interesting stats about the size of Supercell. This article claimed they only have around 150 employees but are slowly expanding at time of publishing. The most surprising stat was that supposedly only around 15 people develop Clash on a regular basis. Also, it states that they outsource all of their support.

15 people seems incredibly low for a game that is so popular. I can't help but think the game would be so much more if they had more people working on it. What says you? Do you think that is enough for developing future clash features?

It's a brilliant concept- small, dedicated, and friendly teams are most effective at executing the games. It's in the name. Supercell- a bunch of small developer cells, dedicated to their specific project, make of the company.

I'm shocked they didn't all retire. Instead it will be a few years of trying to recapture past glory ...

If you think about it its smart, not only is the game developed by people who play the game but its easier to interact with one another opposed to if they have 1000 developers
