The only sealed game I own is Spaltterhouse. Reason for that, is that it was the game came packed with my Turbo Duo system. It sits in the Turbo Duo system box at the moment.
I nearly forgot, I also have a sealed copy of TV Sports Basketball. Reason for that, is I bought a sealed copy, and sold off my worn copy. I've not had the itch to play the game since acquiring it, so it stays sealed. Eventually I'll open it, that also is currently packed away in my, box of turbo grafx game boxes.
I open sealed games, because to me it is a bit pointless to have a sealed game sitting around. I generally don't seak out sealed games, unless the price is reasonable and it's a game I don't have, OR my current copy is a bit worn (torn manual, sunbleach, stickers, etc) and I'd like something in better shape. I prefer to buy complete games in great condition, though I don't buy these games as investments to sit sealed on a shelf somewhere. I have them to play. There are better things to invest in.
I've opened many sealed games the past few years, since getting back into the Turbo grafx in 2003 or 2004. Some of the following sealed games I have opened:
- Jackie Chan's Action Kung Fu
- Order of the Griffon
- Legned of Hero Tonma
- Super Star Soldier
- Dynastic Hero
- Fatal Fury 2 (PCE)
- Y's 3
My feeling is that if you are looking for an investment, want to open a museum, etc leaving it sealed may be understandable. Though, I suggest not being too concerned about those things and jsut play the game if that's what you like to do.
