I mean, they are getting over a million dollars a year, so I don't know that it's unreasonable to expect an actual game. That's enough money to easily pay 9 skilled experts as a studio. You're telling me 9 highly qualified people can't make a half-decent game? I'm not flaming the devs, don't get me wrong, but come on...
Where are you getting the number 9 at? They employ roughly double that from the last time I checked if their linkedin is up to date. You are treating a million as if it is alot without factoring the cost of the space they rent yearly, taxes, hardware and software upkeep and cost, insurances for various things and then the employee wage.
Takes a team of over a hundred people to release a halfway broken triple A game in the time they've been making theirs with an actual team in the double digits. The first few years they hardly had more than the founder and co founder.
You may not be hating, but you're putting it into a pretty simplistic view based around money and thinking they're taking home huge profits when they are probably just comfortably sitting above the red and slowly building a nest egg.
The pay ranges for the type of people they employee go anywhere from 40k to 60k euros a year or even more if they're in a bigger industry. I have no clue what he offers his employees, but I doubt they're being low balled and he is most likely paying over half a million in wages every year if the 16 team count is accurate on linkedin.
