I’ll grab this, because free, but I’ll be the voice of dissent and say I really didn’t like homeworld. I felt like adding a third dimension increased the effort quite a bit as you obviously need to select an x, y axis and then designate a z axis as well.
It never really felt like it offered proportionate rewards to the mental and physical overhead. As an RTS, it felt fairly similar to any other RTS, and the third dimension seldom felt rewarding to me.
I feel like it really needed done harder science fiction momentum to make you really use the space to your advantage or add some softer science fiction tech that would reward formations and angles of attack in a meaningful way.
