These two charts turned up today, reportedly from a "recently scraped database of 24,000 videogames to determine percentages of genre and platform releases since 1975".
My inner stats nerd just fainted.
Charts like this can tell you a lot about games and the changing way we enjoy them, and even allowing for the fact it might be built on iffy data, there seem to be enough general trends checking out that it makes for closer reading.
The "arcade" sections on both make for grim/sad reading.
