So I had already purchased the original Backstory Cards, which seemed pricey but were pretty decent in play. Since I'm currently running a space opera game using Uncharted Worlds, I thought I'd try these.
There are fifteen new cards, a two-page PDF. For a $5.00 price point, I'd have thought there'd be more meat. The cards themselves are OK, but not that amazing or creative. This is a $1.99 product at best. I see now that they've marked down the price on the physical deck + PDF to $5.00, which might still be high, but does me no good. As it is, I feel ripped off. Caveat emptor.
My recommendation is to skip this one and any other Backstory Card supplements at this price point.
