Ah thats interesting, im so sick of all the launchers i have to use now to play games.
I loved Doom Eternal and completed it last night, tho i will agree with you that there are a few confusing elements to it, i'm an original old school Doom fan and have played every PC version of this game and at no time has it ever been mentioned that he lives on his own floating space station that was originally part of another planet, theyve basically just made up a story and called it Doom Lore. As it stands tho it was a great game, slightly frustrating at points but otherwise enjoyable.
