I get what you're saying, but it's still somewhat hypocritical to level the metric of game length against some titles rather than for them when they're more or less in the same genre. It does depend on the content, like say if it's 20 hours of monotony and repetition then I can see why length wouldn't be a good thing, but to be perfectly honest, Dead Space, as good as it is, has a ton of monotony and repetition as well. Any corridor-based shooter does, which is why they're not typically 10+ hour campaigns, because you'd get sick of it regardless of how good it was. Dead Space even has a ton of backtracking which I generally hate. But, again, if I had to do that for 10+ hours I'd be pissed.
