You know, you get a set, and throughout the build you make this strong attachment to the model. So much so, that after you close the last page of the instruction manual, you keep going. Keep building on it, making it your own. Thinking of what missions will this mech go on? Is it a fighter? Will it work in construction? Exploration? That's what this set was to me. The way it's designed, if you have the right technic pieces you can add on just about anything to it. I upgraded mine to have a spring loaded cannon on its arm, extending barrel for small watt laser fire, upgraded foot pads, a better targeting computer and radar along with heavy armor in some places. The possibilities are endless!!! And I have to say, when you pour the pieces out at first it can seem daunting because it's a LOT of little tiny elements, while almost no actual bricks. But the build itself is rather easy, with bigger frame parts holding everything together firmly. The figures are great, Good to see the old space logo again. And the cute little turtle (who I've named Donnie, after my favorite turtle) is very fun and pose able, and I remember making a bunch of them when I got the Lego Adventure book years ago. Not to mention, one of my favorite Lego designers, Mark Stafford helped complete the design before release. :) The only downside is the figure itself is a little off balance, the weight seems to center a little towards the rear, so it can just fall over for no reason. Nothing a few hoppers and some 2x6 plates won't fix though. Also, some of the little extras, like the generators, antenna and the computers that cover the shoulder joint are very fragile and can fall off very easily, only because they're only attached by either a small hook or on one stud. Other than that, GET IT ASAP BEFORE IT RETIRES!!! If not for THIS mech, then for your OWN mech, as I'm sure it's entirely possible to make something completely different from the pieces contained in the box.
