I'm not sure how to answer that, to be honest. It varies depending on the choices you make, the path you take, your reading speed, whether you take your time or fly through it... 

It isn't the longest of games, though, if that's what you're asking. I wanted to tell a tightly paced story, with no fluff or extraneous subplots. Only you can tell if that would be to your taste or not.

Personally, my first full run took around 4 to 5 ish hours, but I have a fast reading speed, so it could be a bit slower for others.
