Like any rpg, but not for character creation, but for whatever?
A few old RPGs tried to make it possible to import characters from the previous entry in the series. This generally didn't work very well, and those were first-party games; to do it for a third-party game seems a lot harder.
But this wasn't just the same company, it was, with some incremental modifications, the same game engine, and by the time the last entries came out, it was showing its age. There's no way you could have taken, say, a character—or even an item—from a completely different game like Ultima VI and turned it into an NFT that could then be added seamlessly into SSI's Secret of the Silver Blades. The two games, despite both being RPGs that came out the same year, are just so completely different that it wouldn't make any sense even if Origin and SSI did want to collaborate on making that possible.
