I rather like what he said. It is completely reasonable in my opinion.
Here is his full response:
"Yes, no f**king shit, I make games for a living," he said. "If I didn't want to earn money from them I wouldn't charge money for them. I like the business model of 'I want money so I make something that I think is worth money, and you pay me that money and you get the thing, and we're all happy' That's it. There's nothing complicated or hidden here."
"If you don't think the things I make are worth the money I charge, that's completely ok," he added. "Don't buy them, or wait for a deep sale, or go the sneaky route and get them for free or whatever, and please tell me that so I can adjust the prices for whatever I release next."
