Thanks for your answer. Factually, kickstarter is not a business model, it's a way to get some seed money from future players. Once the game goes out you still need to have a business model.

Making a game can be an artist job but it also can be a business which is expected to grow, fast and strong as any business.

I found the use of the word "greed" extremely opinionated. Is CEO of Amazon greed ? Greed let suppose that it's accumulating money in a selfish way, which seems to be a pretty bad stuff. I might not understand the nuance as I'm not a native english speaker but I find really strange to link the desire of making money with the "greed" word.

You are maybe right, maybe it's only possible to consider video games as a sustainable business with freemium addiction. I really ask the question
