Sweet, especially if they are indeed DRM-free. I had an Epic account and launcher already, haven't run it for a couple of months though. This was good enough reason to run it again. I had AA and AC already on Steam, bought for peanuts from some Humble Bundle I think back in the day...
Epic is becoming like EA Origin, in which I also amassed a sizable library from their freebies alone. :) I wonder if EA is still offering more freebies? How about UPlay, I think I got some AAA freebie from them too half a year ago?
teceem: Sounds like you can just zip up all the Epic Batman games and have DRM free copies.
The real test to confirm that is to download all the six games, zip them, transfer them to another PC (with no Epic launcher, and never having any of those games installed there) and run them there. If they still work fine, not minding missing registry entries or such, then I consider them DRM-free indeedy.
I am going to test that, just about to download (and install) all the six games on my Windows 7 PC, and then move and try to play them on my Windows 10 PC.
