I'm re-reading my old Super PLAY magazines from the 1990s. Since before the Nintendo 64 was released in Sweden/Europe, and after it had occurred, the magazines were full of ads selling imported USA and Japan Nintendo 64 consoles and games.
Then, in one issue in the later half of 1997, they included a small note about how it's now illegal to sell imported Nintendo 64 games in Sweden (but not to import them yourself). After that, all the following issues of the magazine have all mentions of imported Nintendo 64 games removed from all the ads.
However, they continued to advertise the sale of imported games for PlayStation, Saturn and all other consoles except for the Nintendo 64.
I find this extremely weird. Did they really pass a law in Sweden in late 1997 which specifically disallowed the selling of imported Nintendo 64 games -- not just video games in general? If so, that's the oddest/most specific law I ever did hear.
The magazine in question always seemed to "barely tolerate" what they called "grey importers", so they never mentioned this again that I can remember/find. I have no idea how I'd find out the details of this today.
