How Long Before A Game "Overstays Its Welcome"?

[the-pi-guy]

I don't believe this is a general thing.

It all depends on how fun it is, and how much fun you can get out of those mechanics.

I would not want to play a 100 hour Uncharted game. I would happily play a 1,000 hour Elder Scrolls game, as long as there were enough mechanics and story to keep that experience interesting.
