$120,000 isn't really alot for making M&B development a full-time job. However, it may be a ton of money in Turkey ... I don't know the exchange rates/value per dollar.
Anyway, as a salary, it isn't a lot. Consider that you have to keep working under the pressure that if you do not enhance and develop, you don't earn a living. Plus, the rate of income can be very variable. Armagan and his wife took a big chance doing this. I am glad to see that it is working out for them. I am also glad I have M&B to play
I hope everything continues to go well. I still can't believe a husband and wife team made such a great game themselves. I know, there are other artists now, but look what they accomplished alone to start.
