I was very poor growing up, and mostly played rented games at friend's houses. The first game I bought new with money I earned was Chrono Trigger (from 92' - 95', all the money I earned from working went to help out my family, so I was able to get CT in '96). After that I started picking up things I had missed out on like LttP, Mega Man X, etc., and went all in on PS1.
Throughout the years, I'd pick up games here and there from the 80's and 90's, but other than the GBC, GBA and SNES games I had bought in the late 90's and 00's, my cartridge games were cart only. In 2016 or so, I decided to go CIB only, and I've been able to make that happen. I love the artwork, the manuals, the adverts...all of it. There's almost a ceremony in unboxing and getting ready to play a game, and that's what gets me every time; I'm comfortable with the incurred expense to get those great feelings of opening a game, reading a manual, and playing even today, especially since that feeling was so elusive when I was a kid.
