I've stumbled across a few sealed games in the last few years. One of them was Fantasy Zone, I believe. Another might have been Parasol Stars. Anyway, I open them up right away. To me, sealed simply means "complete and in great condition". There is no way I'd ever keep a game sealed. I don't buy games simply to put on the shelf... well mostly to put on the shelf, but I play everything I own without exception.
Now give me your Tiger Road. I still need that one.
