Is there any way to do this? I would like to keep track of hours played.

thought the same - i tried renaming several .exe files but of course it didn't work that easy :) if someone have a solution for this i am also intrested

Yeah, I tried that too.

First of all I don't know if this still works or not however you could try following the instructions listed here:

No i don't think it will track your in game time however i could be wrong.

Ok, thanks fot the info. That's pretty much what I thought. I was pretty sure there was a way to launch it through gog, but tracking hours was the main thing for me. It works the same way with steam.

Yeah, the Beelzebub Mod is fantastic, I think. If it's that important and renaming doesn't work--use an OS clock timer application and create a txt file and add to it daily as you play. But it may not be *that* important to you, after all...;)

Yeah, I don't think it's that important to me lol. Belzebub is amazing, though! As someone who played vanilla since '99 or so, it's a game changer! Never really got into mods too much, but I noticed a lot of people mention it on here so I decided to check it out. Very glad I did :)
