I don't think it is a completely different discussion. The length of the game affects length of development time, the available budget that they can spend on a game, etc. There are all sorts of effects on development, which circles back to me not feeling the new Halos or the new Assassin's Creeds are as good anymore. I hardly consider length of a game at all in how I feel about it or prefer it, as long as feels like it should be that long, which comes back to pacing again.
