Even though I religiously watch ZP, I actually haven't bought a new video game in probably a year, and nor have I played one, either. I still play games, mind, but only my old ones and one certain online game.
So whenever I watch ZP, I really have no basis of comparison to the game. Whether or not I like it, whether things that bothered him bother me, things like that. I've seen every episode, and I guess I keep watching because he is witty and reliable. When he really lays into a game, he always manages to find a different or creative way to put it.
Yahtzee knows a thing or two about comedy, it's apparent in his work. Even though his opinions are serious, his presentation never fails to include proper timing, enunciating, and joke-callback to give it the entertainment we expect.
Wathcing ZP is kind of like watching The Soup on E!, I guess. The host there is kind of a jerk, but he's a funny jerk and gives a proper slap in the face to those morons and douches that are clouding up the celebrity lists these days. And, you don't even have to agree with him to find the entertainment value in what he says, or at the very least, how he says it.
