Everything I said in my review of the main game (Doctor Who: Adventures in Time and Space) apply to this supplement as well. An absolutely fantastic product. I hope some of the other companies out there are paying attention - these guys are definitely setting the bar for top quality design and production. When you pay $30-$50 for a game, THIS is the sort of thing you should get.
I love that besides the overall quality, they hit all the right buttons! I'm not left scrambling to fill the rules/fluff gaps - all the tools and info I need is right here. Amazing stuff.
