Most hours spent on one game?

Wow, I just checked my time played on Runescape and apparently it's 11295 hours... and this is actual active playing since the game automatically logs you out if you don't click for 1 minute. I wonder if that includes the time played during Runescape Classic (an old version of the game which they discontinued after they ported over all the characters to the new version). The number is probably quite a bit higher, since this is only on my main account. I have a lot of time spent on other accounts.
