It looks like Horizon on Steam is NOT DRM-free the way the Epic store version is. I ended up getting it on Steam because I've been burned by Epic games having DRM added in updates, and unlike with Steam, you can't downgrade Epic games, so I'd rather have the Steam client if I have to have one.
Truth007: I wouldn't be surprised, epic seems to be better at having drm game free titles than steam.
comicbookguy90: At least for the bigger titles.
Also some one mentioned able to get Sonic Mania drm free? Was there an older version of Sonic Mania that was drm free?
Sonic Mania isn't DRM-free now, and to my knowledge, it's never been DRM-free; in fact, it used to have Denuvo. Who mentioned it being DRM-free? That would be an amazing discovery. If you're talking about my comment above, I was just talking about downloading and old version of the game, but I was specifically trying to get a version with Denuvo so I could test something.
