Obviously Kickstarter doesn’t give backers an ROI, but beside that, what’s wrong with using Kickstarter as the Kickstarter for video games?
As much as the big publisher model trends towards games that feel somewhat alike and tend to chase trends, it moves the burden of risk onto an entity that's designed to assume that risk.
By and large, it's pretty easy on KS to see when a campaign is created by known developers/publishers. But there's still plenty of noise and anomalies, like this "Day of Dragons" which seemed to raise half a mil based on coincidental timing: https://www.eurogamer.net/articles/2019-10-11-harry-potter-a...
And Fig seems to be way more specialized, since it also offers to act as a publishing.
