Yeah, the video puts a LOT of data together, but I don’t think that it reads it correctly and the conclusion is skewed. At a certain point, it says “for every brown game, there’s a Just Dance or Super Mario game to balance it off”, which, sure, it’s technically true, but nobody ever accused those games to be brown in the first place.

There certainly was a tendency in using a more prominent brown/green filter in games during that time. The video posits that it may be due to gamers aging (something along the line of “a player playing Kingdom Hearts on PS2 who then grows up and plays Gears of War on X360 may wonder where the colours went”), but I remember a lot of series turning brown that weren’t before: compare Ace Combat 4 to Ace Combat 6, Resident Evil 3 to Resident Evil 5, and even Call of Duty 2 to Modern Warfare 2.
