I think all of you make good points.

My personal collections have always been limited, except for now. I officially started collecting (not counting toys that were played with) when the Transformers Alternators line came out... that was the only time I ever collected to complete, and that ended when they released Optimus Prime as a pick-up truck. Since then I have collected 25th Joes, some Spytroops/VvV, and very few JvC. I also randomly collect anything that looks cool, or that I feel fits into my Joeverse.

My 25th collection alone numbers at over 400 figures, including repaints, doubles, and of course army building. I know from here on out it will only grow with both the movie and more Resolute figures being released. I still collect the original Joe vehicles for my "green" repaints or the Cobra vehicles for my "black" repaints.

Point is my collecting days of anything but GI Joe are numbered, I myself have decided to sell my Clone Trooper army of 98 figures. Half of which has already been sold on Ebay, and the other half is up now for auctions selling in groups of 5 figures.

I don't think I will ever stop collection, but I know I will limit collecting.
