I was sent a 54 card promo deck, and let me tell you, I'm fairly impressed with it, and how useful it could be.
Now I doubt I would use it as a low-rules system, but I know for a fact, I will be using it for the italicized use. Nothing is easier for fleshing out an NPC than throwing a card down to determine what their personality is. If they're a random NPC, no reason to have to figure out how they think when you toss a card and bam, instant imagery and play style.
The deck was nice for a promo deck, and if the quality is as good or better than this you'll be getting a deck that will last for quite a while.Since I run a lot of games at conventions, I know I will most likely get lots of play out of this promo deck.
Also, since the kickstarter is already over $4k, the deck is going to be 90 cards, and if it hits over $6k. There will be a 36 card expansion on top of that. So if this sounds like something you want to jump in on, well jump on in.
