First, it finally gave me a chance to build one of the humanoid styled TAGS from the infinity line. To date I had only build the Maghariba guard spiderbot thing, and it was exciting to work on such an awesome looking figure.
Secondly, I like building larger models. They may require a significant amount of pinning thanks to being large and metal (in the Dragões case, it required ALL OF THE PINS), but the joints are generally larger and easier to access, and allow for a much more satisfying final product.
Thirdly.... IT'S GOT A GIANT DAMN CANNON! BOOYEAH!
Seriously, it's an awesome figure.
