Topic on Talk:List of DRM-free games on Epic Games Store
I didn't see any way to edit this page (I'm new to this sort of thing) but I've been testing some of these games by removing them from my Epic Game Store folder and disabling my internet before attempting to run them.
I figured that for now I would use this post to list any games that wouldn't run properly without the internet and/or Epic Game Store.
-Riverbond (after launching, was given an error message about not being able to connect to the Epic Game Store. was not able to get to title screen or main menu)
-Shadow tactics: Blade Of The Shogun (When I attempted to launch, it showed my epic game store tab, then the game simply closed itself. This may be DRM or just a bug on my end, but I figured it's worth mentioning)
