As it stands, I’ve put in 2,600+ hours and written 62,176 lines of code (mostly C++). The game’s made $27.92 in income, which nets out at about $0.01 per hour.
It is a sorry state for indie game developers; actually, the state would be the same even for the apps. But, on an average, I believe it takes significantly more effort to think of, design and implement a game. The race to the bottom on every app store out there is for sure to blame. Going indie full-time is becoming harder by the day. Especially so for new entrants.
I seem to have arrived very late to the party, and there are broken bottles and passed-out revelers everywhere.
I think many indie developers will share this emotion.
