Sulibor: Do you know if it requires Origin launcher to run, or - once downloaded -, launcher can be uninstalled? The PC Gaming Wiki just states “Origin” in the DRM table on the game page, but I never used this launcher so I am not sure how it works.
It requires Origin to be running before the game starts. At least it does for other games like the original Mass Effects, Dragon Ages etc., so I'd expect this to be the same.
If you attempt to run the game with the client killed, it starts up Origin login window. If you uninstall it completely, I think it will prompt you to install it, although not 100% sure about this one. And the games probably wouldn't work without it anyway as the first thing it does after you launch the game is also connect to the EA servers.
