Well, as a fan of DN3D, but only having been slightly aware of the concept of Duke Nukem Forever until a couple of years ago, I still found this video to be hilarious. In fact, I think this is the most I've laughed at any of Yahtzee's videos, which says something because I tend to find his reviews to be pretty funny already. Of course, I knew it was a joke from the beginning, because I've been following some discussions about 3D Realms and DNF lately.
as a huge fan of Duke Nukem i found that review kinda... insulting? i don't know, this is the first time that any of Yahtzee's reviews have ever touched on a game that was particularly close to home.
If you've watched all of Zero Punctuation up to this, you must understand by now that this is the way Yahtzee does things. It's almost inevitable that he'll eventually get around to a game that actually matters to you. You shouldn't let yourself be bothered by it, because this is what Yahtzee DOES. Even if you disagree with what he comes down on it for, either try to view it objectively enough that you can still laugh at the jokes, or at least ignore it, because he treats every game that way.
