I just found out about this game yesterday and I had to register on this forum to let you know that LAN and Online Multiplayer support should be added to this game at some point.
And Cosmoweazle listed all the multiplayer modes which I had in my mind too. The coop mode might be the most fun amongst our LAN party group for sure. Same with the RTS but with a small change to it => COOP RTS mode so that you could setup teams and decide in which team which player is or are all players in the same faction team and they all fight against AI controlled territories and that way do their own part in expanding the empire of the same faction. This way you could also coordinate attacks to same planet. You just shout, 3, 2, 1 and jump and all players could jump from different planets and different locations to one place and have an epic fight over one planet or everyone would solo their own way expanding the empire from their own corner of the empire and asking help whenever needed from the other LAN players.
Bases would be a nice addition too, in this gamemode and in general to the game when it expands and develops more.
Also the length and size of those RTS campaigns should be adjustable so you could complete them in 2 hours or in 12 hours. Meaning that you could adjust the difficulty and amount of planets in the campaign. This way you could have large easy campaigns, large hard campaigns which would take time or small easy or hard campaigns which could be completed more quickly.
And I would imagine the 3) Coop mode like the base game now but with multiple ships or just micromanaging the same ship with a crew member as a player. That micromanaging though might be hard to implement so that it would be interesting but it might work. But for sure I would like to see the coop mode so that you would have multiple ships always going to same location instead of just one ship like in current campaign.
I'm sure this game will become great. 🙂
