Didnt they already remake DOOM with DOOM 3?
They did, but this is another reboot. You could say the same thing about the Wolfenstein games and Quake. I guess it's just how ID make their games
One thing I'm worried about is the crowd reactions. They're raving about it but at the same time most are still asking for Fallout 4, which IMO will come when it's done. A new DOOM game hasn't been made since more than a decade.
