You reminded me that when the CD drive kicked out the disc for the first time and asked for the next, you knew that you had broken through and that some new shit was about to land.
Riven is why I got a CD drive (Plextor) that used caddys rather than a tray. I knew that I was going to be swapping discs fairly often and the caddy gave them more protection. Every time I went to a new island, it was a furious sorting of caddys to find the right one, then slam it into the drive to avoid wasting time out of the game.
I still remember swapping out those CDs every time I switched islands. The entire experience was utterly captivating as an 13yearold.
