You're likely thinking of something like an FPS/RTS hybrid, there have been attempts but those have been multiplayer. With modern engines and hardware it's certainly possible to get it done and I'd be very interested in that sort of thing too. Really the only tricky thing would be balance, I could easily see some kind of sci-fi sim being like that where you've got ship boarding and planetary combat among other things. DEI devs only care about pumping a live service scam out as fast as possible so it's down to indies to try out stuff like that and see if it sticks, I can see the potential.
