I really doubt Stefan and Unix make much if any profit from Graal.
The main assets they would get from the game are people buying accounts and it's not like sales are booming. Yes they make some from the store thing but not to much I would presume.
Now take the liabilities they have to pay out. The running of the servers and the wages that the people in the office get paid.
I assume that the liabilities out weigh the assets greatly therefore they are losing money.
Running servers can't be too cheap.
