Perplex City was awesome, and I still miss it. It had a really unique storytelling mechanism, the cards were generally pretty fun, high production values.

I thought the second season suffered a bit when they introduced human actors as characters, instead of just illustrations. It lost a bit of charm. And as a Euro-centric game it was harder as an American to be as involved. But it was still a great multi-platform experience. I would love to see something like it again (or even work on such a game)
