Although it is undeniably interesting in a way, I don’t see how this will make for better games — I can see how this will make games feel more like work: an activity in which you justify the time invested in it by the monetary value you can get in return.
And it could be argued that the magic in video games is exactly how they are so purely ludic. An antithesis of work.
