At what point does a game's length becomes an issue?

When you tire of the mechanics before the game concludes.
Not the worst problem in the world, you just stop playing at that point. Its better than the game ending before you tire of the mechanics.

I rather have the game end before I get tired of it. TW3, great game, left a bitter after taste. Instead of being glad it's finally over I rather feel like starting another playthrough or replay certain parts. I did 2 playthroughs of Infamous SS, the length of that was just right for me. The problem with long openworld RGPs is that you're petty much done building your character long before the game is over and levelling up becomes very slow and pretty much irellevant. I know when I'm tired of the mechanics when I stop looting.

It helps a lot when you can play quite different character, both mechanic wise (like say mage instead of a fighter) and moral wise - I love RPGs that I can start again right after I've finished them and make a build that I don't usually play and then be on the dark side on top of it.

While I fairly liked Witcher 3, I don't think I have much incentive to replay it, and why I wish CDPR to make more of a 'unnamed hero' type of D&D-ish game sometime in the future.
