(900 Canadian dollars on lego shop at home)
For me, I'd find far more enjoyment in the Gen 1 sets, even when it comes to building. Case in point: after looking at a single picture of the dark hunter "Tyrant" for around ten years now, I finally built him and it's pretty incredible, having this character that I've wanted for so long. Now I'm imagining building not only Krakua, Krahka, ancient, the archives mole, but everybody; each character coming together completing some part of my childhood. Not only the nostalgia factor, but even the reality of the building experience- hours upon hours scouring bricklink and online instructions to build tens of characters sounds way, way more appealing to me than putting together a milenium falcon composed of thousands of grey, grey bricks.
Regardless of all this, no building experience could even hope to cover the falcon's lost ground when it comes to the final product: falcon itself or the entirety of G1- or even just the 900 dollars it costs to buy it.
