Unknown game variation: !! Limited Edition Sol Moonarage ?!!?

[SuperPlay]

I have 2 CD-ROM Titles that have gold spines.

Kawa No Nushitsuri Shizenha



and

Color Wars




Are these re-release or did they always come with gold spines?

[Necromancer]

Beats me, but it's fishing sim and a rather tame puzzler..... surely they didn't sell like hot cakes and demand a 'best of' printing.

It's quite interesting as both games are not from the same company. I just realised that my copy of Eferia & Jiloria had a golden spine card too (and the grand Golden Axe too).

Sometimes golden spines were also commonly from the begin with. So had nothing to do with the any special limited re-prints.

interesting for me to mention - the "limited edition" golden spines doesn't seem to be worth more, at least at the Japan stores.  I saw another Sol Moon. Golden spine avail, as well as Sprig. Mark 2 with Pink and gold spines... so I guess it's worth noting the variation exists, but nothing to go crazy about...
