I have no interest in Marathon. The only reason I orginally purchased and xbox was the play Destiny 1, if Destiny 2 dies or there is no D3, I have yet to see a Bungie game that I will purchase to replace Destiny 2 in my lineup - but I have seen plenty of other games that will easily fill my time and that friends have moved to, away from Destiny 2.
I totally get that, I upgraded to Series X for this? I'm looking forward to Cities Skylines 2! They made some real improvements, it will be hard to play anything else if D2 servers keep crashing.
