10 to 15 hours for a story based game max. Otherwise it will be spread out over too many game sessions and the story loses its impact. I don't mind longer games though once I'm into them. I guess I spend about 60 hours with The witcher 3, yet after 20 hours I was done caring about the main story. Side stories and exploration were still fun.
Game length does stop me from starting a lot of games nowadays. It's quite a commitment to begin another 40+ hour game. I haven't started Bloodborne and MGS 5 yet for that reason, nor DA:Inquisition or FC4. Oh forgot, still have Batman too :( I did finally finish GTA5, claimed 50GB back on my ps4!
And I'll still get Fallout 4 day 1, I never learn.
It would be nice if developers had the balls to add an actual story mode. Accelerated leveling, abilities reduced to a core set removing the fluff, reduced loot to the essentials, no crafting, condensed story with only the most important side quests. That would give me an incentive to actually replay games like The Witcher 3. Going through the full 60 hours again, or 40, hell no.
A simple choice, how long would you like your experience to last.
