The Kickstarter would be you trying to make a profit via their IP without permission. Expect to get sued into oblivion.
I mean, we would first start the project, and then fund it through kickstarter.com. If the project is successfully funded, we will pay them for their license.
Won't they accept payment by some percentage of game sale ? Like UE4 does for 5% each sale.
Just to help you avoid additional surprises, avoid the term "Super Hero." Note how many alternative franchises use the term "supers" to refer to super-powered heroic individuals to work around the legal troubles.
The comic we have chosen doesn't has any games out there for now. But fans are looking for it. We have our own H&S type story but how many people can we interest with it (like without getting to know the story and just seeing a half finished protoype on kickstarter)?
