Unified environment texture plane (grass, tree leaves etc.) visibility for all players AND AI units. AI should see what players see.
Properly synced time and weather conditions to all players in MP missions.
Option to play through campaigns without touching any High command missions (I hate RTS games.)
New, clear, simple to use gameplay user interface
New, unrestricted save game system so that you don't have to backup your game saves manually in middle of missions. Ability to revert to any save point directly from the user interface.
