I would buy ALL the Narnia sets if Lego ever makes them. I wish they did. I bought so many Star Wars sets, but they were played with and now all the pieces sit in a huge bin. I don't even remember how many I bought, but you could make just about any Star Wars ship and character with all the pieces I have.
But if I were to buy all the Narnia sets, I would build them and never let anyone play with them or un-build them. I would challenge them to single combat if they ever touch them, even if it's a teeny weeny kid.
Baby: "goo goo, nania. gaaaa."
Me: "Little baby, what are you doing with my Narnia set?"
Baby: "goo goo, nania, nania."
Me: "Wait. why are you playing with Aslan?"
Baby: "ga, ga, aalan, aalan."
Me: "That's it! Pick up your sword kid, and step outside!"
Baby: "goo goo AAAAALLLLLAAAAN!"
Me: "What? Do you mean to say you will not give me satisfaction? I'll have you know this is a matter of honor, sir. Honor! (and $29.95 plus tax)"
