Byku But no, here we are with invasive DRMs, always online single player, rootkits running on kernel level and now this.
Totally off topic and tl;dr, but you know there are online shops, such as GOG, specifically selling games that are DRM-free and possible to run on computers without internet. Support them, and you are supporting game developers that are friendly! You get an installation exe file that is yours to keep forever.
Many Steam games work fine too after uninstalling Steam and disconnecting internet, but it is a hit and miss. And you can always refund a game if it turns out to not work without Steam installed and internet connected. I mean, unless the shop page says internet is required or the game has DRM, because sometimes they label that so you know what to avoid.
