Didn't someone earlier in the thread mention that they can't modify orders (it's impossible) once they have been placed? That would mean they can only cancel the order.
Don't get me wrong. If I had the space, I'd probably collect games older than the PS1. However, I wouldn't be crazy to want to own them all. I draw the line at clone games that are only valuable because of their low print.
Yep. Even a decent copy fetches a nice penny thanks to the extremely low print(No more than 10,000 I believe).
As for your purchase, if you just want to play it then it's fine.
