Gon on, as in you mean like to explain the obvious? Just google/chatgpt sales of RTS games vs shooters and other shit.
Good luck convincing an exec to give you 200 million $ to make a new RTS for the 50 player based market out there who's playing the oldies anyway: AOE, RA, SC, etc.
It's a small and saturated market that's long been fished out and no point investing into, other than HD remakes/remasters of previously mentioned established IP.
