I dont know why everyone equates having sealed games to not liking to play games... I too play all my games, but I still have some sealed ones.
I used to open up games as soon as I bought them, even if I bought 3 or 4 at once, I'd open all of them on the way home and read the manuals and stuff.
Nowadays I only open up the game at the very moment Im ready to play it so if I wind up never getting to a game, at least its sealed up and has a little more value if I want to sell or trade it.
I have a bunch of PS1 rpgs still sealed, Dragon Warrior VII, FF Origins, Chrono Trigger & Chrono Cross, etc. Im not trying to keep them sealed, Id open them up in a heartbeat if I decided to play them. But for me its kinda hard to start up a 70 hour rpg so I just never get to them.
