In the post on Steam, Facepunch Studios urged players and creators to help them remove every trace of anything Nintendo-themed from Garry's Mod.
It was originally thought that the DMCA requests coming from 'Nintendo' were false and were being circulated by a malicious operator, but Facepunch Studios confirmed that the requests are legit and come directly from the legal team at Nintendo.
Many users are now wondering what took Nintendo so long to make this formal request.
In the past, the "refund timer" would reset on an early access game's full release, allowing players with hundreds of hours to get an automatic refund when a game moved to full release.
