Look, I get it, you don't like piracy, no company likes piracy, and the guy you're shutting down was really sketchy, but Nintendo, you haven't done hardly jack shit to preserve your older games library.
Instead of Virtual Console the Switch has a substandard subscription system that was last updated with games nobody even remembered or cared about, you made Super Mario 3D All-Stars a limited release for some bullshit reason, same with the long-awaited English version of the original Fire Emblem, and there is still no word on new systems coming to Switch Online.
Nintendo's thinking is as backwards as ever. -_-
I have a very hard time arguing that ROM sites are in it solely for "game preservation" when they carry the ROMs for Super Mario Bros, The Legend of Zelda, and other Nintendo titles readily available from a multitude of legal sources, all the while using Nintendo's mascots likeness all over their sites to promote them. Last time I checked, Super Mario Bros, The Legend of Zelda, etc weren't in any jeopardy of becoming "lost media".
Also, for all the outrage about Super Mario 3D All-Stars not having unlimited copies printed, they clearly printed enough that it's still readily available for purchase from Amazon, Target, Best Buy, Gamestop, etc.
