My biggest problem with DNF is that they pitched it as this high-quality experience, at the same level of quality as all of Gearbox's other outings.
It wasn't. Not by a longshot.
Now, granted, they couldn't exactly advertise it as "a buggy, clunky, uneven, overbloomed mess that showed every bad design decision that made the game take more than a decade to emerge"... but unfortunately that's what it was. I bought it on sale for $10 on Steam and played for exactly 109 minutes before I just absolutely quit in disgust- by that point I was rooting for the aliens to hurry up and destroy the pathetically moronic humans that populate Duke's world, because I sure as hell wasn't having any fun trying to save them.
It's been said before, but I'll reiterate. Duke Nukem Forever tried to be a parody of itself, its own sordid history and the franchise's colorful glory days, but it seemed like every last joke fell flat. And without anything else to support the experience- like, you know, good gameplay or story or graphics- it had nothing to stand on.
