If you look, these last years they've been going at it around the time of the releases of NES Mini, SNES Mini and now the Switch Online service, with its "free" NES games with online features, although supposedly they would expand to other systems. They also said that Switch wont have a "Virtual Console" in the same way the Wii had, so who knows what they'll do.
Personally I kinda doubt they'll do a good job about offering good retro-game stuff with Switch, even if they had a typical VC system on play. Back in the Wii days they put quite a bit of effort to have a good selection of games, and companies with these old games found in that a way to make money and give new commercial life to these games. Good for both. We even got quite a few obscure games, it was great (Except if you lived in Europe/Australia, fuck 50hz).
But that's
not going to happen again. Maybe Nintendo lost interest with the Wii U, maybe the other companies found better to make mediocre ports of their games themselves, like Capcom and
Squeenix, maybe both, but the selection on that system was much more shallow. Soon we will lose all the Wii VC (and Wiiware) content, and with that Wii U will also loose
more than 200 exclusive games through the Virtual Console on Wii, almost all of them third party stuff.
By now companies like Sega have their own plans, like Sega Ages on Switch, or their deal with AtGames to make mediocre Mega Drive knock-offs with Roms installed. You have Capcom selling collections (ironically, the Disney NES collection wasn't on a Nintendo platform, which would have made the most money), and Hamster doing their Archive Arcades. And then we're starting to see ports of Wii games, like Go Vacation or the DeBlob games, among others. I hate to say it, but I think there's no place for Virtual Console any more. Other companies have their own ways to make money out of old games, making Nintendo's VC ecosystem rather useless for them.
Maybe if you only care about a tiny chunk of Nintendo-owned games, and while that could be okay, that's disappointing when a decade ago we were getting things like freakin' Castlevania: Rondo of Blood for first time outside Japan. Of course, that always-desired Game Cube VC could still be interesting, but not even close to what we had. We may not even be able to buy the games themselves, and will only be a gamepass style service.
And all this becomes even more disappointing when you think about a Wii-like effort for a VC system on a HD
portable device with mutiple controller options, easy multiplayer access for a good chunk of the systems it could support, and other perks the Switch has.
...
Anyway, those sites weren't only being attacked by Nintendo lately, other big ones were alongside them (because as I said, selling old games became way more viable thanks to VC in the first place). Another company that forced those sites to remove their games was for example Square Enix, in many of them you couldn't find most of their old games, or had their links removed, which is kinda funny because that company doesn't get mentioned as much.
I understand them going against such places, it's their copyright and all that. Legally they're obviously in their right to claim their stuff. Not to mention certain places were heavily trying to make a profit out of hosting ROMS and getting way too popular to ignore them. But at the same time I can't help but to think it's quite hypocritical to some extent, too.
Emulation has benefited them in several cases. I highly doubt Nintendo would be making profits of series like Mother (through VC releases) or an even better example, Fire Emblem if interest for those franchises weren't ignited thanks to emulation letting the creation of fandom outside Japan. And does anyone really think those NES and SNES Minis would have sold as much if they weren't easily hack-able and it was possible to expand the number of games by inserting ROMS?
Nostalgia only gets you so far; yet NES Mini was the
biggest unit seller in the US back in June of this year.
Yes, it sold more than the Switch and PS4.
Heck, let's go full circle. The Virtual Console wouldn't have existed and become profitable for them if interest around old games wasn't maintained and expanded thanks of emulation in a big, big part.
