It is pretty long, I would say those 50-60 hours.
Couple words of advice
- use OTS (over the shoulder) camera
- read tutorial screens and learn the right timing for combat, select hard difficulty (at least try it)
- invest some points into Aard sign, it makes final boss of first chapter much less frustrating
Hard to give any advice to such post. For me it doesn't suck in any of the three games, although TW2 has weakest combat (still fun). Most importantly though, combat is not what these games revolve around.
Hard is the only way!
Did my first play of TW3 on hard and boy i didn't know what i was in for
