@PhenomX6 @meso @Zerglingman @Silly_CB Going full-freetard when it comes to gaming is pretty stupid though. There is nothing harmful about decades old DOS games or NES ROMs, no matter how much the FSF claims they are also unethical.
Also, the FSF still considers scripts (which games often use for events, AI, etc) as software, so even playing otherwise proprietary games with libre replacement engines, or games where the data is still proprietary (assuming the data has scripts) are still considered unethical according to the FSF. Scripts shouldn't be a problem because they are usually sandboxed and only work within the context of the game, but the FSF believes that all proprietary software is unethical, so your options are pretty limited.
