in Unity you have to pay those $$$ when you already get 100,000$ income from your apps (but there are no event sheets, nice stuff and so on)
anyway I guess that now SCIRRA 80% money gets from yearly education licences... so we might not be the real C2 target:
100 independent devs x 79 pounds = 7900 pounds *one time*
100 schools x 159.9 pounds = 15,990 pounds *yearly*
