How A Fake Video Game Screenshot Is Made

[Technician]

Consumers are smarter today than they used to be, but that hasn’t stopped video game publishers from releasing what have become known as “bullshots,” doctored images that are meant to show what a video game looks like, but end up being so modified and fancified they’re often nothing of the sort.

Don't get too upset, the Big Mac you get at McDonald's isn't going to look anything like the poster either.
I don't think anyone still thinks that product images are the actual product anymore anyways, or expects it to be. The article is kind of funny though in that the author seemed surprised at this revelation.
