Rockstar haven’t said yet how long they expect GTA 4 to be absent from Steam.
Back in 2018, Rockstar pushed an update removing a number of songs from GTA 4 due to expiring music licenses.
“Grand Theft Auto 4 was originally created for the Games For Windows Live platform,” Rockstar say in a statement to US Gamer.
Now it’s been delisted from Steam as well, though it doesn’t actually seem to be related to any grand plans Rockstar have for their own launcher.
Just in time to launch Red Dead Redemption 2 on PC, Rockstar announced their own game launcher for desktop.
