@Alex @xianc78 @TerminalAutism Fan games more so than ROM hacks.
Even back when I was lurking around on ROM hacking communities (mostly Mario Kart DS and Mario Kart 7, Mario Kart Wii, New Super Mario Bros., Super Mario 64 DS, and several Pokemon focused ones), even the people active on these noticed how Nintendo was swinging their lawsuit hammer like a motherfucker against fan games, piracy sites, JewTubers, flash cards, modchips, custom firmwares, and even emulators, but they've left ROM hackers alone for some weird reason.
