Hilarious, I also thought the "I am a monster truck who walks like a man!!" line was a great contender for quote of the decade.
What I have heard though is that this game doesn't try to claim it's not stolen from other games, but rather that "this is the Zelda game we always wanted to play, but that Nintendo were to f*ing 'no we must make all games cute with cheery voices!!' to make". The Zelda game mechanics have been mentioned in every review, article, preview or anything I've seen on this game, and I'll probably buy it once the PC version (which I have heard is coming out sometime in the future, probably before DNF) is selling for a reasonable price. Like 5? or something.
To me, this game seems really enjoyable. And this ZP episode was the funniest I've seen for a while.
