I've been reading up and I read that one person here beat the game in 23 hours. There are only 4 acts right? Right now im starting act 3 going pretty slow and im only on hour 6 so are acts 3 and 4 longer? I've watched every cutscene too..

I believe there are 5 acts, not 4. I am about to start act 3 and I think I am somewhere around 8-9 hours.

I like to take my time.

I think that they are 5 acts, and im also 6 hrs in at the beginning of act 3, 23 hrs is nothing to sneeze at. In the age where the single player portion are usually short (COD4) and a series like MGS which have never been real long (not to me anyways), 23 hrs sounds great

Yea, I'm happy with 23 hours, I just was wondering if i was going too fast.

This isn't an epic RPG, 23 hours is more then sufficient.

23hrs? It only took me 16 and a half. But yeah the farther you get in the longer the cut scenes seem to get

 does that include cutscenes?

yeah every single one

16.5 hours is great, there is nothing this gen that is longer while still being part of the same genre(Action/adventure/shooting).
