I agree with Gok. Toys are meant to be played with. The only downside is when an arm accidentally gets twisted off.
When i get a new one i play with it for ages then it goes on the shelf. Sometimes whole lines get pulled off the shelf and live on the coffee table for a week while i play with them.
I like toys. I'm currently in the process of moving so they're all being bubble wrapped and packed and i hate seeing them like that. All imprisoned and without weaponry etc.
I understand people like keeping them mint in box/ on card, i could just never bring myself to do it.
