607 Hours = 25.291666666666668 Days
For Alene: 7979 Hours = 332.4583333333333 Days. (Almost a year)
Let's take the amount of days since Warband's release (not taking into account anything related to the beta): It was released on the 30th of March 2010, so let's add up all the days since its release:
2010: 365 - 31 - 28 - 30 = 276
2011: 365
2012: 366
2013: 365
2014: 31 + 28 + 31 + 24 = 114
Total: 276 + 365 + 365 + 366 + 114 = 1486 days since release
332.4583333333333 Days/1486 Days = 0,224
22,4% of the time that Warband has been released, Alene has been playing!
