@Tfmonkey It's a rare game to get in good state. Even then it's fairly pricey.
I'm considering selling my copy of Shadow of the Colossus for PS2 since I now have a CFW PS3. I'm valuing the space more than the physical games I own.
@Wopu I have the Jojo Bizzare Adventure game on PS1. I just thought it looked fun and knew nothing about the anime. Now it's worth a lot.
I bought a lot of PS1 games back before retro video game collecting existing and they were giving away last Gen games for $1.
@Wopu Yeah it was Shadow Hearts. I still have it. I have a substantial PS1 and Gamecube collection that's probably worth something.
