I'm having a bit of a think myself though - I'm probably never going to have my dioramas (if I could even call them that) back up and even if I could I'm not sure that I should lest I risk throwing myself into them at the expense of other things I should be prioritising. So conceivably I could reduce my collection to having only so much as I need to represent the characters and vehicles on a one-of-each basis - as opposed to the multiples of characters and multiples of certain vehicles that I have at the moment.
An easy one is to get rid of my prequel toys which are taking up space in the attic. I wouldn't miss them at all. The OT stuff would be more of a challenge to cull. ''But I like that green A-wing, but I have a particular nostalgia attached to that outdated Boussh Leia figure'' etc etc.
