The bird studio people and toriyama in particular need to sign off on every reissue. Ie: the people on the game’s copyright. Thus it’s not something square can put out on a whim, and why the wii vc reissue was basically a miracle. (This is also why a lot of enix stuff is blocked from reissuing, as the devs of most of those co-owned the games… and in the case of quintet, the IP owners vanished entirely after actraiser 1’s wii release. Not even beginning to get into the composer of soul blazer owning the music, or the IOG artist owning the art on top of that… so yeah CT is tricky but even then way easier than anything quintet or almanac made, which i’d file under impossible)
It’s also why say, SMRPG cannot be released by nintendo alone and needs squaresoft’s approval to make happen since they own the software and characters
