The unanimous game of the year last year is a turn-based RPG, and I can promise you Metaphor: ReFantazio this year will do well critically and commercially, just like Like a Dragon: Infinite Wealth did earlier this year. There are plenty of turn-based RPGs to go around. If you meant turn-based tactics or strategy, same thing; plenty of those to go around as well.

RTS sort of peaked with StarCraft II, at least in terms of popularity, but you find some here and there. Battle Aces and Stormgate are both from ex-Blizzard devs chasing that high, and both are live service, so those two will soon be dead, but there are others out there that are less popular that come out from time to time.
