Why my roblox is not working and he say it's not working goggle  play store  is calling me and to upgrade it ;(

The RTS genre was very popular back in the day with games like C&C, Red Alert, Dune, Warcraft, Steel soldiers and many more. But over time these games fizzled out alongside the genre. I think the last big RTS game franchises were Starcraft and Halo Wars, but those seem to be done and gone now. There are some fun alternatives, but all very niche and obscure. I've heard people say the genre died out with the rise of the console, but I believe PC gaming is once again very popular these days. Yet RTS games are not. Is it a genre that younger generations don't like? Is it because it's hard to make money with the genre? Or something else completely? What do you think?
