Hi Bungie, you're the creators of the old Mac game Marathon right? I have Marathon Durandal on my Xbox One. It was backwards compatible and able to be played on the Xbox. I want to know if it's possible for the first Marathon and Infinity to be able to eventually be made available to be played on the Xbox One as a downloadable game. I would play it on my Mac but I have Catalina on my Mac currently and for some reason Catalina is not able to open Marathon when I download it. I'm not sure how playing the game from a CD-Rom works. I have a DVD player and am able to insert discs on my computer since I have one of those DVD players that are separate from the Mac itself (plugs in with the help of a USB) but not sure how a game on a disc is able to work on the Mac I currently have. Any help or insight would help. Just a simple yes or no will suffice if it's possible to do or not. I was shocked when I saw that Durandal was able to be bought from the Xbox store since it's a part of my childhood. I miss that part.
