I've been throughly enjoying Homeworld 3's campaign.
I am half way through the campaign, and it's a beautiful experience. Often literally—it's extremely clear the artists at Blackbird put a lot of thought into exactly what you see when you first warp into the mission. It's gorgeous.
The story is also quite good so far. I like the protagonist and her side-kick, "Intel," (lol) and I'm excited to see what happens next.
