since i started using gog galaxy i've found myself not caring whether the game was originally purchased on steam or epic, and the EGS free games over xmas were a nice get.
i just hope in all of this developers get a good return out of this too.
I used GOG Galaxy for the free Rayman Legends game I got on the Epic Store.
When I clicked install it:
1. Started EGS as a second client.
2. Notified me about an update for EGS that I installed.
3. Opened up a view where it had me login to uPlay, to link those accounts.
4. Opened uPlay as a third client.
5. Notified me about an update for uPlay that I installed.
6. Notified me about an update for GOG Galaxy that I installed.
7. Launched the game.
8. Left all three clients running after I exited the game.
I still care where I buy my games, after user experiences like that.
I'm still going to pick free games on EGS from time to time, but I've had zero incentives during 2019 that make me want to spend money there.
