Epic CEO Tim Sweeney previously revealed that the company pays a flat fee to each developer to give away their games, rather than paying per download.
Your download doesn’t give the developer any money. The fee is already paid. The Developer gets just as much from you if you pirate their game, or more if you go purchase it on a different platform instead.
That’s like saying “in my opinion”: it’s unnecessary. Of course it’s your opinion or you wouldn’t have said it, and of course that was true last you checked or you wouldn’t claim that was the case.
If someone’s information is out of date it is appropriate to correct them. It is absurd to expect people to do research before posting anything about anything to make sure it is “up to date”.
For example: did you double check that you can in fact still play games off-line using Epic before posting? Or did you just assume it was true based on “last you checked”?
