I was wondering how many hours I invested into my two main characters, and that made me curious whether the Sentinel files I saved for all my characters before the shutdown recorded the amount of time played (the info one could see by talking to a civilian whose name began with M*). I've replaced my PC since then, but if the data is in there it would be worth it to me to dig out the old hard drive.
*Is it sad that I haven't played this game in 6 years and yet I remembered which letter without having to look it up?
