Just got the beginner game, and though I haven't finished reading the books yet, or have yet to play a game, I have a couple of impressions upon what I've seen so far.
First off, the box, I was kind of dissapointed in the packaging. A sturdier box with a lift off lid would be better suited for this type of game. The box is likely to be reused once the game is over, and the thin, tabbed lid box is just too flimsy.
The dice mechanic, despite looking more complicated than it actually it, it's brilliant, and I can easily see how it would speed up gameplay.
That being said, there aren't enough of the dice included. (Yes, I know there's 14, and that's a lot compared to other games.) But, I've noticed that there are some skills that list dice pools of 4 green ability dice, but the game only includes 3. There's also difficulty levels of up to 5 purple difficulty dice, but the game only includes 3 of these as well. I could also envision an encounter when players can come up with good reasons to have mulitple boost dice (or you could rightly add setback dice), and there aren't enough in the Beginner Game to accomodate this.
Hopefully soon, supplimentary dice packs will be available to remedy this deficiency.
Other than that, the game looks good, fast paced. The rules allow for quick & dirty encounters without a lot of calculation of modifiers and such that sometimes bog down other games, and allows for off the wall narrative events that happen all the time in the movies.
