I honestly grew really bored of the hobby, got tired of waiting for Sideshow to produce more HPP suits (the last one was Shades from summer 2017), wanted more space in my bedroom (I share an 1100-square-feet apartment with one roommate, and the figures, boxes, and Detolfs took up an unconscionable amount of space in my room), and perhaps most importantly...I came to the realization that there were far more fulfilling ways to spend/donate my money.
Decided to keep my three favorites...Marks 6, 45, and 46...and keep my pre-order of the Infinity War suit, and liquidate the rest of the collection. Still can't believe how quickly these things got bought up...80% of my collection vanished in less than two weeks.
