Quoted from Msch:The Walking Dead theme is way more popular than Kiss is, was, or ever will be. Theme means nothing without it being a good game. If you disagree with th fact that Walking Dead has a bigger fan base, has made more money, well....dad....look at the numbers.
You're comparing something at the height of its popularity to popularity over the long haul.
I'm not even a Kiss fan, but I think in 5 years Walking Dead will be pretty much forgotten. How many times can they run through the "find a safe place, see it burned by bad people" thing before everyone is tired of it? Just like CSI and 24, it will be relegated to the odd staleness of canceled TV show pins. Its a double whammy if the game stinks. I've seen the complaints, but haven't played it to know.
Kiss has been around forever. They might not be at the pinnacle of their popularity now, but they stayed popular enough to keep going. The Kiss pin *looks* killer, right up there with the best Stern has ever done.
