I am not a big RTS fan so i can't really speak on terms of a gameplay perspective, but the story in those games are some of my favorite parts in Halo lore, to the point i wished Halo 4 and 5 story wise was based on and replaced Halo Wars 2, instead of the stupid forerunner-promethean -Yoink- we got. But still keeping the relationships and characterization we got in 4. Not 5 though. But yeah, great series story wise, dont see why it got nuked, especially when it was barely marketed. Like its someone elses fault that they thought an RTS would get sales for just being a part of Halo lore lmao.
