Darament:I think I spent about 6-7 hours playing it through on heroic. the only thing that made the game long was going through the second time to finish getting all the black boxes and skulls. right now I have something like 257 hours logged in the game total but thats nothing compared to other games i've played. I guess for your average player it would be longer to complete the campain. almost every RTS i've played has had 2 campains at least. Starcraft has 3, command and conquer has 2 and sometimes 3 depending on which one you play, Age of empires 3 has 3. i'm trying to remember others that i've played but I can't. but they have all had at least 2.
IMO the idea of having multiple factions with their own campains is to show off the strengths and give a player a more rounded experience so that if they were to take it to the MP side of the game then they could have a better understanding of how to play either side. I believe that if they would have put in a covenant campain it would help with the whole people playing covenant more in MP. I would think that a good deal of people play the campain before going into the MP game and thats where most of their experiences come from.
dont you remember halo wars was a basic form of an RTS its not meant to be comparible to high end RTS games that have been out since 1990-2000. and i have never played starcraft but the more campaigns you have in a game and the more missions you have the more the quality goes down both visually and story wise. while halo wars was meant to focus on simple controls stunning game play and its online battles, so quality was important and the control scheme you can consider the campaign an extra bsides no othe campaign leaves the door open for a sequal
Aloysius:If you think about it, Galactus is a giant purple alien who eats planets. Kind of like the Covenant.

It's official, straight from the mouth of an employee who works on Halo.
The Covenant eat planets.
