Something I see when I look at my collection of Transformers is how incomplete and worn they are. And unlike a lot of collectors, I don't mind this. I don't need perfect toys, sealed mint in box. I like knowing that these toys were played with an enjoyed as a kid.
I remember some decades ago, when a friend visited my apartment with her son, he started playing with my Jetfire figure. She said "you probably shoudln't play with that." I said "No, it's quite alright. Just be gentle and don't break it."
Toys are meant for playing with and enjoying. Sometimes, enjoying them is keeping them in a box to look at admiringly. Sometimes, it's transforming all your guys into Devastator and flying him around the house.
