That’s totally fine but it should be opt in, or just prompt you when you launch the game for the first time. It doesn’t ask and then actively breaks things for some users.
Another big win is game licences work for anyone using the console for all games. While some PC publishers require each individual user to buy another copy of the game in order to keep separate profiles. Looking at you, Ubisoft
I can second the hijacking thing. Steam has its own controller input driver (?) it installs which sometimes clash with the actual drivers for the controller, which can lead to games registering input twice or not at all etc.
You can disable it but sometimes it randomly seems to re-enable itself and it’s super annoying.
I played through it at launch on my lower end gaming laptop (1050 GPU) that I had at the time. With some fiddling, and basically turning everything to lowest I got it to just about playable framerates.
Massively enjoyed the game and its universe. I hit a few bugs but nothing that was hugely game breaking, at least nowhere as bad as people were saying. I also managed my expectations knowing my hardware at the time was low-end/dated.
Then I saw footage of the game being played on base tier PS4 and Xbox One hardware and holy shit, if I’d bought it on either of those (especially Xbox), I’d have been furious. The game was not ready and should never have been released for those consoles. It clearly needed at least PS4 Pro or One X to even be remotely playable at launch.
