If you've played Dark Souls for any significant amount of time, you've probably died in Dark Souls a large number of times. And now there's a site that will tell you exactly how many times. To, you know, get hyped for Dark Souls II.
To get your death number, you have to visit the Dark Souls Death Counter and upload your saved game. The site is only for the PC version (aka the best version ?) right now (this is a fan-made endeavour), but I expect the scope will broaden soon as the ability to pull saved games and game data off an Xbox 360 with a thumb drive is a built-in feature of the console's OS.
The site also has collected the data from save files folks have submitted so far to build some interesting graphs, but these are of course not representative of the entire playerbase.
