This is the first Lego set I've purchased and I'll be honest, I only bought it so I could have the mansion, Tony and Pepper, and DUM-E with his fire extinguisher. The Mandarin, Extremis soldier, and copter went right onto eBay. So you're partly right on people buying it for the minifigures. lol
Nobody told me I'd be bitten by the Lego bug and end up trying to expand the mansion to look more like the movie version. The workshop should be downstairs not in the living room! I have to wonder why Lego didn't do a workshop set and a mansion set so the two could combine. I would have bought them.
This is a great review, and I love your sense of humor. Looking forward to more reviews!
