Make a game that earns the price of the thing you want to buy
Noch nicht übersetzt — hier steht die englische Fassung.
If there is something you want to buy soon and it feels a bit expensive, make a game that aims to earn exactly that money.
Say you want the new PS5 Pro. Then make a game that aims to earn $900 net. If the game is $3 and you sell 600 copies, you have earned enough.
