Sounds like a pretty short game for the money. To me, Gothic 3 was a step in the right direction. It was flawed, but felt more like a real place than the previous games. 30 hours is too short.
No 30 hour is the norm now. Don't you know the motto of today is don't waste my time. 40 hour games are a thing of the past man.
Just for reference read this article titled -Opinion: Don’t Waste My Time
