Quality isn't the be-all, end-all, but there's definitely a correlation. Flappy Bird wouldn't even have gotten off of the ground if there were problems with something like collision detection. Even something as simple as increasing the delay between rounds (by as little as a few seconds) could have hindered its success. The game is not without merit.
