Just for fun a made a list of all the games on my Xbox Live Gamercard. then weighted the % complete of each game against the difficulty as specified by achieve360points.com. into what I’ve dubbed the “hardcore score”.
UPDATE: This is the spreadsheet calculator that I used to extrapolate 1-5 difficulty scores into 1-10. Since not all games had a 1-10 score but those that didn’t had a 1-5 score vote in the forums.
hardcore indeed!
