Deathloop is Bethesda and it was pretty much done when MS bought them. Same for Ghostwire Tokyo, Starfield, Wolfenstein 3, Doom etc. Those will never count for MS because they had fuck all to do with any of them getting made. It will be the same with COD.Flight Sim, Halo, Psychonauts, Forza, Deathloop. Pretty good year. Not even including PC.
Idk what you mean by Returnal winning all the “major awards”. I know Resetera used to have a tracker thread and last I saw in it, Returnal was beaten by three or four of those MS games I listed above and also It Takes Two. Maybe that changed, idk or care.
FlightSim is 2020 so if you want to add ports then you have to add Ghost Of Tsushima and Death Stranding DC to Sony 2021 (87% and 85% on meta)
