I do have plans to play almost all of my games...eventually. I just might not be able to do it until after the heat death of the universe.
One thing that I do feel really factors into my collecting is the idea of trying to make up for lost time or missed chances when I was younger. As a kid, you couldn't get new things very fast; you were limited to holidays/birthdays, saving up allowance, and on occasion, the rare treat. So, the entire smorgasbord of toys and games wasn't available to you, it just came on a drip feed. And now that I'm an adult, the only thing stopping me from spending my money on this stuff is effectively me, and it shows. Now that I'm able to complete collections, I want to make it a reality instead of a pipe dream. At times, it does feel like I'm trying to impress 10-year old me, but that's alright, as it's still all stuff I actually enjoy.
I'm with you on this. However I kinda burned out on videogames and I feel like I have to set a timer on to actually get a good session in. I kinda enjoy the other aspects of life more. like working, learning Japanese (which ties into playing video games). recently mostly collecting right now in hopes I get interested again. It's not a waste of money if you keep the games and what not in good condition since you can thin out or completely sell collections. It's the same with me, I work now and at times can buy in bulk! I missed the N64 era since I was born in 1996, so I collect that and want more Super Nintendo goods.
