The difference here is in special scenes, which don't affect the main story anyhow. I've never cut out a single animation or a render from the main game just to include it in another version. If the guys want to see a scene they vote for, they can subscribe to a higher tier, if they just want to see the main game and be informed about the development process- they choose a tier they're comfortable with. And all my patrons, each if them, are treated with equal respect. They can always count for support, getting answers for any questions they've got, early access and other benefits. I've never left any of their questions unanswered or ignored them, and I'm sure all if them can confirm that.
