The game system is, when all is said and done, pretty wonderful. There's nothing really new about it, but the game mechanics are simple, they fit the Doctor Who spirit and genre extremely well, and they make the game a joy to play.

Were there any specific things you wanted to know about or discuss?

Good questions, mate.

To answer the first, it's realtively easy to stat up NPCs. If one is creating a new alien species or creature, that may take a bit longer (depends on what you want the creature to have).

Balancing the NPCs with the party is another trick. Bear in mind, that in theory, there isn't really a balance in characters. I mean, take Rose and David Tennant's Doctor...there isn't a lot of balance there, is there? But the game handles that rather well, to be honest, by using a simple character generation system that allows you to have more points for characters, or less. Tennant's Doctor has the Time Lord (Experienced) Trait multiple times to reflect his experience. Rose, on the other hand, has the Inexperienced Trait to reflect her life at the time she started travelling with the Doctor. That said, the game system does have its own form of balance, in that the system for creating characters works well.

The system is very much what a game that simulates and attempts to catch the feel and flavour of Doctor Who needed. It is very much intuitive for the most part, although the uses to which Story Points are put adds a very interactive GM/Player element to the game.

Any other specific questions you might have? I'll do me best to answer them, and will try to post up an example of character creation shortly today.
