Or Command & Conquer, which didn’t had as strong of a competitive community comparatively, but were very successful through their fun story campaigns. Also, there’s some pretty successful real time 4X titles too that very much hit mainstream audiences, despite being even more of a niche due to their scale. I think a lot of RTS games often tried too much to compete with the esport niche too, trying to replace the established titles, which is kind of an impossible task. Doing an RTS that doesn’t aim for this goal can still be successful however, if one puts the focus on that instead of targeting unreachable heights.
