Didn't get the Mario LEGOs, but I would have to get these ones. I love the idea of sucking up ghosts with LEGO Luigi.
HWYR if a proper LEGO Sonic kit was released? There are three sets (Green Hill, City Escape, Tropical Resort) and they come with different characters and props, an Eggman boss fight, a couple of Chaos Emeralds (7 with all three sets combined), obstacles like robots and hidden goodies like Red Star Rings, the actual pieces to make your own version of a stage, and a goal post? (Plus there would be other neat details. Sonic has detatchable Soap Shoes that let him grind on rails, he can stand on each of the Emeralds to go Super and have a ring countdown and invincibility, there's intractable loops in Green Hill, snowboarding down City Escape, wisps in Tropical Resort, etc etc etc, trust me its fun).
