I do... I got my GF addicted to them. Ordered the Lego Bank last Friday (double vip points weekend) and got it on Tuesday. She is still building it. She has a ton of Star Wars, some Ideas, etc. She builds off exclusively using instructions
Me, I like the technic stuff, and some of the basic city series. I also have a ton of misc models built. At 35, I still make the sound effects when building. You can still play as an adult.
