It’s confirmed that there will be new content coming out this year. I think it’s better to fill basic game mechanics first than new leaders or maps. Besides, if they add forge mode or map editor the game will be super replayable. Agree or disagree as will. Btw I’m not English speaker so sorry for poor English expression.
I don’t think a custom game browser would work for Halo Wars.
Agreed with the above comment. I don’t see how customs would work in Halo Wars. The settings players have to play around with are not nearly as customizable as those in the FPS games. It wouldn’t lead to many interesting games.
