I was just thinking a few days ago that it is surprising flappy bird didn't get invented much earlier. In terms of complexity it seems to be somewhere between pong and Asteroids. Games like Pac-Man and steet fighter are much more complex. Yet flappy bird came out in 2013. Wikipedia puts "Helicopter Game"[0] from 2003 as the first game with flappy bird's game mechanic.[1] That still seems a bit late to me. Am I missing something?
