Well, since I'm still into comic books and video games, I never really let go of my childhood things I loved.
I do, however, miss rental places. Browsing through the movie categories that were chock full of stuff you never heard of. Renting the latest game coming out. Getting free popcorn with our purchases. Arguing movies and games with the workers.
Heck, ours even had a sort of console arcade. They had all the big systems at the time (NES, SNES, Genesis, Sega CD, Saturn, N64, PS1, and even Jaguar) set-up to play. You could play any game they had that wasn't rented out. You'd pay by the hour. As kids we spent a lot of money there.
