I was just wondering about how old the player base is on average. Because it's a ten-year-old game, it's feasible that some gamers grew up playing Diablo 3 with their parents and are now playing Diablo 3.
I'm 42 years old and have been playing since the game's release.
I've been playing Diablo since Diablo 1 came out in the late 1990's. I'm an old fart who still loves gaming. Since I'm 64 and retired I have lots of time on my hands to play Diablo ( and other games ) lol
There is no strong language or sexual content in the game itself, though public chat is always a source of things that require parental supervision, like language, potential bullying or stalking. 18+ (15+ in the UK) seems a high age rating, but the average votes here of 10/12+ is a little on the low side.
