Quoted from benheck:Licenses are important to pinball. And as Chris mentions above, having to create assets from scratch is tough.
Also most original themes aren't original, they're just rip offs of known licenses or tropes. MM is Holy Grail, No Good Gophers is Caddyshack, AFM is every 50s movie, etc. So people know the basic premise when the step up to the machine.
When you do have a truly original theme like Dialed In people warm to it very slowly, though a large part of that is their fault for not pushing a disaster theme.
Yes, was thinking the same thing. I like the creativity, but a lot of the unlicensed pins if released today wouldn't standup to a lawsuit.
