It's not sealed. I wouldn't buy it if it was. While I like sealed games for my collection, I can't justify a purchase this big if I can't even play it. It's priced at $700. He's had it in his shop for over a year, and recently he took it home to "cook" for a few years. When I noticed it wasn't there anymore, I asked him about it and he brought it back to the store for me. I don't like the idea of dropping $700 on one game, I just sold a handful of games that I've been sitting on, so I can justify it as if it's a trade.
I was only assuming there were several runs of bootlegs. Looks like I worded that part of my last post poorly. Reading through some of the older topics here, it seemed like there might be some EverAnime and Son May bootlegs too, plus multiple runs of the PCE Works ones. If it's just the Care4data and PCE Works ones, I feel pretty confident I'll be buying a legit copy then.
Thanks so much for everyone's help!
