It's fun when you read an article about lego changing and realize that the author is old enough that the "new" legos he's talking about are actually the legos you played with when you were ~6-7 years old.

Take it from an adult raised with "new" legos, if your kid has some imagination, it does not really matter if the kit is made with simple bricks or more complex pieces with a rudimentary mechanism, I had ton of fun with those.
