I mean, if compare the $$$ value, 99% of these Patreon stuff are not "worth it", especially when a full fledged indie game is normally only $5-$20, AA is only $20-$40, AAA is $60-$90.
You basically pay cuz you like what you see and want to financially support the project.
And if all of this games' contents are only "timed exclusive" that will be available for free later, then it's more like a "bonus" to incentive.
(Tho there are devs who exploit Patreon to milk as much money as possible, that's not all of them and deserved to be called out)
BTW, I'm glad it's not "an actual movie", game is a much more engaging and immersive form.
