Robette: Sorry, but I very much get his reasoning. Game development, especially indie game development, is a ruinous industry with people earning scrap on average, unless they literally got the most outstanding game of the year going and a good bit of hype.
From what he describes, epic just offers much better conditions. I'm not interested in the game and I treat epic exclusives as non-existent, since I never bought anything on this platform, but as a dev who has to pay bills, I would probably take that deal too.
As I said earlier, I personally do not complain about his life or business choices (Epic exclusivity, etc). He is human, he has a family and they have to live. He knows better how to handle that.
What I don't understand is why they don't release the first game here, DRM-free, after selling it for years on Steam and even giving it for free on Epic. It has even been released on every console that existed in the past 5 years or so.
