why didn't they just improve forged alliance ?
more realistic looking units
improved graphics
better engine
sort balance issues
add in some new units like they had so many in TA
add possibly another race or two
better AI
more music
take away commander teleport(anywhere) ability...he teleports to enemy commander with lazer and its i die and you die...cheap draw tactic.
different modes of play...something like 8 ppl start a game in random positions and you are teamed with 1 other at random. would be fun trying to support each other from different parts of the map.
[optional] some kind of tech tree promotions where you choose a certain path to perform better for the role you're playing in the team.
tbh they could have even threw some dinosaurs in there.....giant T-rex dawn of war style (not serious

).
