RPGs don't sell well. I wish EA would realize that.
?
I know the following games aren't monocled cRPGs, but they are recognisable firm RPG genre material that draws attention to and further interest in the genre:
From the Wiki list of best selling games OF ALL TIME (all platforms):
Skyrim
Diablo III
And browsing the by-platform lists:
Final Fantasy (lots of editions)
KOTOR
Morrowind
Guild Wars
World of Warfare
Basically all the titles you'd expect to see on the list. Bioware was on the verge with Baldur's Gate II, which apparently sold a cool 2 million copies, when 2 million was a very cool number, just out of reach of the all-time numbers, likewise The Witcher series with similar numbers and, of course, Everquest and Dragon Age, to name but a few from a couple of lists anyone can quickly search. Even the Black Isle titles amassed near a million sales and people often falsely parade these as under-performing titles, which is highly incorrect.
I don't think there's any proof at all that RPGs don't sell, quite the opposite in fact, which is why people keep making them. As Divinity: Original Sin recently proved, there's a good 1,000,000 people out there who will buy a decent to good RPG. If 1 million isn't enough to be considered more than "don't sell", then fuck what I'm drinking, I want what you're injecting!
