There is definitely a problem of over-specialization of parts in the higher-level kits these days, but on the other hand you get a lot more interesting parts these days to build in really creative ways. It's amazing how well each part is designed to do different tasks. I've built a lot of the Star Wars kits and they do use a fair number of the same type of parts. But there are certainly a greater variety.

I am a huge Lego fan, and I'm super-jealous of the guys who can order this. I tried, but my wife put her foot down. So I created http://www.BuyMeALego.com to trade links/ads for tiny donations. If you know a small business or blog that needs more traffic, send them my way!
