Ideal length of a game

[50]

Anyone think these massive world games are too long in length? I find it more enjoyable to play and beat a game that takes about 20-25 hours more than one that takes over 70 to just see the main story. I know for some it's a matter of how much game you can get for your money, but I think many find it more appealing to just turn on and play and FPS that requires no commitment to the story.

3 hours in the SCHÜTZENGRABEN is the best time for maximum fun and entertainment

I really believe that 30 is really enough. I usually don't even play games that are 40+ hours. 
Or I it has to be really 9,5/10
