All I will add is that your comment regarding "market distortion" basically outlines the issue I have with Epic. I don't blame developers for taking deals (my beef is with Epic only), but I really think exclusives should be discouraged in every industry. Most of the biggest companies in the world used the same or similar strategies, so I really don't have high hopes Epic will make things "better" in the long run. I hope I am wrong about this though.
Anyway, I do want to avoid any further discussion since this topic can get very heated easily and I would be derailing this discussion.
Just to balance this out, I actually did stumble on this post by asking google if "Itch.io accepted AAA games" in hindsight it was kind of a silly question to ask (IMO) since it would go against what Itch.io *is*.
Bigger indie games I feel would give the platform the most leverage since I imagine Itch.io has this stigma that it's just for "amatuers" or for "small experimental titles". Maybe if enough people shop at Itch.io or even simply engage with the site, we could see game jams or events appear that give developers funding or resources to make/finish larger projects.
