Because lego produces new sets every year to keep the toy line fresh. This set was on retail shelves for 3 years. Lego wouldn't have room for new sets if they didn't retire sets after they've been out for a long time.

The package says age 6-12. I bought it for my 5 year old grandson. He "helped" his Papa out it together. It does contain alot of small parts. My grandson loves it.
