That’s not a long time ago, not when you consider it takes multiple years to make a game. They are in the current era of Xbox, and just one generation back. MCC is still receiving content now.
The ‘Optimsied for Series’ version of Gears 5 was essentially a light remaster, as was the update for Forza Horizon 4. The entire back compat philosophy of upping frame rates and resolutions – this is no different from what many Publishers have sold as full price ‘remasters’ in the past.
Saying that these don’t count as remasters because MS provided them for free is an odd position IMO. Pricing doesn’t change what it is.
My point stands – there is nothing in MS philosophy today or in recent years that paints a picture of a Publisher than doesn’t believe in remasters and remakes. The opposite appears to be true.
