Why in the HELL would we want to waste our time duplicating an RTB build to prove a point? It IS possible to build that in retail, yes (and if you doubt that you're a moron), but the time and effort it would take would be immense, and the outcome isn't worth it. Aside from that, the build isn't anything special anyway, the only thing it has going for it is its size, but what the build boils down to is just stretchy stretchy lattices.
The differences between Retail and RTB are clear, and to compare them would be idiotic; the games are totally different from one another. Go play RTB if you want to build realistically, play Retail if you want to build with LEGOs.
Oh and I read like 1/4th of the thread so if it wasn't already an RTB vs. Retail war I guess I just started one :/.
NINJAEDIT: ProBuilder you're a friend.
SLOWEREDIT: What the hell, his build doesn't even look like the real thing. Hey buddy, why don't you focus on actually building yours ACCURATELY before you start flaunting the build like you're Jesus Christ.
EVENSLOOOOWEREDIT: Hey Wedge you seem to enjoy researching. Remind me to come to you if I need homework help :D.
