Just like the titles reads. I answered "both" because I mainly display my Transformers but, have a couple of extras of a few Transformers that I like to "fiddle" with. I don't necessarily play with them to the point where I make them interact with each other with "voices" and "pew...pew...pew" noises. (Although there's nothing wrong with that either. LOL) So do you play with them, display them, or both?
