To answer the original question, my collection and collecting habits are starting to change, something that was caused recently as I decided to dismantle my dedicated game room so that I could turn it into an office. This decision was brought about by some other major changes in my life that happened this year, it will be a great year.
By getting rid of my game room, the amount of space I have for my collection has also decreased. As a result, this has made me take some steps that I knew would come about at some point, i.e. paring the collection.
A few things I realized is that aside for the Switch, I really have little to no interest in gaming from the 7th generation of consoles onwards, and even my interest in the sixth generation is limited. So I'm going to ditch almost all of the Xbox / 360 stuff, and casually get GC games that are fun or iconic. Sega Dreamcast I have the most interest in from that generation, ironically enough, so that stuff will stay.
Similarly, I have little interest in the SNES. I will just keep iconic or gamer stuff, ditch the rest.
