You're missing the point by a country mile. Infinifactory and Factorio are both primarily about creativity. You make stuff in both of them, and by and large solutions tend to be quite individual. Maybe not so much in the tutorial levels of Infinifactory, but once you get to any of the complex problems no two solutions are really the same.
People have done some really oddball things with the sandbox mode of Infinifactory. Notch made a Turing machine, for example. It's bulky and terribly slow, but it functions.
If you don't understand the appeal, fine, but maybe then you don't need to bother posting in threads about either game, hey? Surely you've got better things to do with your time.
