As I already said, in the cases where the game has parts that are a grind. Keep the good parts, take out the bad parts, you have a better game. Shadows of Mordor is a good recent example for me. Great game, awesome combat, pretty good main story arch, but it started to wear a little long and I had to force myself to finish the end. It would have been better if they trimmed the fat.
Hm, it seems that I cannot make my point clear!?!
Of course, when a game is bad...it is then better for it to be short. But we are not talking about bad games. And the longer a game does not automatically makes it boring.
If the grinding in shadows of mordor is boring, the question is: do I need the grinding to progress, do I need the grinding to unlock gameplay stuff. If one of these are answered with yes: bad game design...the devs should improve and spice up the grinding to make it fun. The length is in this case not the problem. If it is just for getting trophys...this is different than and not problematic.
I hope I make myself clear?
