I still watch it every week, but yeah - maybe it's just a tired format, maybe we just need Yahtzee to give his opinion in another style.
What strikes me these days, is that every game sucks if it isn't what he is into - I wish he could be more objective sometimes. I especially don't like how he tars every military FPS with the same brush, and often fails to see the points that make some games stand out. I guess I'm talking about Battlefield3 here mainly, which I thought was an amazing multiplayer experience, unpredictable (mostly), and a lot of fun. Instead he painted it black because the single player sucked... seriously, a Battlefield game had a shitty campaign?, is/was anyone surprised by that?
Maybe his tastes are a bit more distinctive these days, and auto-trolling games that don't exactly fit the bill is becoming old. If you look at Minecraft, sure you can talk about the simplistic visuals, somewhat stupid mobs, repetitive nature... or you can talk about the world of possibilities, the hardcore survival mode, the incredible depth of exploration. I think gamers these days can be a lot more forgiving - willing to make do with visually less impressive indi games to experience different gameplay mechanics.
A lot of people respect his opinion, his proper opinion, not what he rants through in ZP - perhaps we'd rather hear his real opinions these days and leave the trolling to the YouTubers. In fact, I think I prefer his retro playthroughs more than ZP.
