IMO great games with great campaigns beg to differ. Also there are a lot of FPs experiences that do give us longer and better campaings. The Bioshocks, the Metroid Primes for example.
Also the best of the FPS campaigns are either short and good enough so that want to play it again after you beat it( Short good/evil type FPS or short action games are good for this) or are long and have enough content to be satisfied with just one go at it.
