Yeah, but the hardware specs used for both Samaritan and Infiltrator are way beyond even cutting edge. They are tech demo's.

And you would most likely have to get a commercial liscence, depending on the terms the engine owner has. Most game engines' liscence assumes you will be distributing the executable.....but a few have terms loose enough that they -might- be able to claim percentages. And the same goes for end stage renderers. There is no easy answer because of the contract gobbledygook that is standard......
