You can also design your own units and when you play against the AI against that faction, the AI will use your designed units.
Still dislike this very much. I build units that are meant to work in cohort with other units. 'Glass Cannon' style. AI does not know this and will just build 'Glass' part. Wrecks games.
Imo, there should be a 'check' chart in the menu so that before you start a game you can choose what units are to be made available for the AI to use. (minus the default units of course....gotta leave AI with something)
This can be extended into the steam cloud aswell (as much as I hate steam) whereas a player can connect and choose units from whoever uploads unit designs to the cloud. Obviously there will be trolls designing crap units and uploading them too, so you'd need a 'check' chart to filter through the options.
Same approach should be done for user created sovereigns and factions.
If this were done.....it would be a definate 'wow' factor, even with the steam intergration....I would be one step closer to converting to using steam IF steam also changed there EULA to allow for game resales and manual update options and complete game disconnect...where you don't need to be in steam to load a steam game),
