I think cynically there might be some motivation from executives, because if you remake a classic game that helps you sidestep the woke curse.
If you make a new Halo it'll inevitably be about trans vaginas with a metaphor for Trump thrown in.
Imagine being so fucking lazy that instead of just making old classic games optimized for modern tech you instead go out of your way in remaking it into something that it is almost always worse and have the balls to charge $80 for it.
The industry is creatively bankrupt.
