Concise and playable
Having cut my rpg'ing teeth on classic Traveller and being turned off by rules systems that get too granular, I have to say I like Mongoose's release. It's concise, to the point and easy enough to get into quickly. I never was much into the roll-up-a-character thing and prefer the point-based system, especially when I already have a concept of who the character is and need to model him/her to fit the rules. As for the ship mortgage and other financial details, it's really up to the GM and players how much that appears in their adventures. It's a nice stick (or carrot, I suppose) for the GM to use on the players from time to time, but to deal with it session after session...nah.
I agree with the review about the lack of background material and would like to see a campaign setting supplement, though that may be where the Spinward Marches supplement comes into play.
