Hmm what to say.
Well for pieces, its passable. Worth the money I think. Certainly the figs and their accessories come in proper amounts, including the inclusion of a shield for every fig. The black studless plates are always useful.
Design? Eh, considering that Lego has to make these sets appeal to little kids, as well as "us", they did an okay job. The catapult does what all little kids seem to like, but it actually shoots a decent sized rock. It's design is much more, well not realistic, but certainly more believable. It actually looks like it could hold that rock. As opposed to certain sets where the catapult is strapped to the side of a horse.
For the price it's at, I would say this is worth it. I certainly have no big qualms about mine.
I build, therefore I am.
