I was led to believe that if I import it to Steam later, it will launch the launcher only which is then inconvenient via Steam Link... I will look into it, as otherwise I can't wait.![]()
Aye, you have to run the launcher to run the game. Even the direct game shortcut that R* creates on install won't work - it throws up an error saying "Please run Red Dead Redemption 2 from the Rockstar Launcher".
For Steam Link, I guess the advantage of waiting is that the process would be effectively automatic, because if it's anything like GTA V it'll run the launcher and automatically launch the game, directly from Steam. But you can just as easily add a non-Steam shortcut to the R* launcher and then click 'Play'.
It's up to you really.
