I just found out that on average, 1/4 of iOS games and 1/8 of Android games (most Android games are trashware) make $5,000 a month from ad revenue. I hate working multiple real life jobs and still making under $30,000 a year. I could make addicting toilet games and get $50,000-$100,000 a year.
(Flappy bird, Angry birds, Subway Surfers, and other simple but addicting games are toilet games. These are apps that you play to pass time, when you have nothing else to do. They have a difficulty curve where losing is common, and ads appear when you lose or win. This speeds up the ad revenue without being annoying during gameplay.)
I could either make a toilet game, or a game that gives you coins for watching ads. I feel like the time for retro indie games is popular. People love 16bit and 8bit games, but what if I go even further and build an Atari style game? I built Turk Hunt in a day, and I could have put more time and work into X-vioas, but the point is, retro games are in demand right now, and luckily for me, Atari art style is the least time consuming art form. I'll update this topic when I get home. That's when I'll start concept art and make a name for the game.
