In the past, I haven't cared about HuCards being loose, but I already have the Turbo Magical Chase and if I'm going to buy the PCE version, I'd like to get the case with manual so I can scan in the artwork. A few years ago though, I would have jumped on this, even in the condition it's in... if the game was going for what it is now complete.
Also, now that I believe I literally have most HuCards, after only casually picking up games when I come across them... I'm not in a rush to pick up loose hard copies over other PCE CD games and am happy just playing any HuCards I'm missing on my Everdrive in the meantime.
