Yep, I am a little bit of a completest - on certain lines however only.
Around the middle of Super Link/Energon series I realised that I could not continue down the path I was heading down back then (Japanese and American of both series) so cut back to the best series (normally Japanese) OR first out the gate (ie, Classics)

Some of the suggestions just don't fit in with my 'personality' - if I haven't opened something in the first 2 months of it being in my collection then there is a good chance that I will never open it even if it was purchased to open. So having a storage shed full of toys doesn't bother me until the storage shed got full (really full). As I said before, I have images of all the stuff I have in storage and look at monthly as a reminder.

Most toys released between 1984 and 2011 I have played with a version of it somewhere down the line. The 8 months I spent unemployed did change my habits a bit.


Based on the feedback and my own thoughts
So far I could get rid of (if they sell) Masterpiece MP-1, MP-2, MP-3, MP-3G, MP-4, MP-6 and MP-7 since they have made better versions, as well as the bulk of my Alternators.

I can actually see myself eventually getting rid of everything aside from G1 and MP-8 onwards but .. that will take major amounts of time and I guess I need to very slowly release items from the collection into the sale list rather than dump and hope.
