Unless you're an old school gamer who has been playing video games since characters were so pixelated it was hard to tell what they were you may not know how far game resolution has come.
Or you may have seen game graphics improve over the years but never had the difference visually spelled out for you.
Well, you can't get much clearer than this- here's a screenshot from Wolfenstein 3D (1992) and one from the more recent game Wolfenstein: The New Order (2014).
In Wolfenstein 3D you couldn't even see the look on the Nazis' faces when you blew their heads off!
The difference in game resolutions should be obvious when the games being compared were made 20+ years apart, but the difference between Wrestlemania (1989) and WWE 2K15 (2014) put me down for the count!
