Heya, nice to see you here, Beyogi!
I was going to write about how in-character the Helghan government has no idea Comstar is anything other than a phone company that leveraged its monopoly into a potentially somewhat worrying degree of power (depending on how much public knowledge our ambassadors and spooks gathered), but
@Forgothrax beat me to it.
That aside, it's honestly a weakness of how
@prometheus110 has handled diplomacy in general so far, as it is quite rare that other factions initiate diplomacy or agreements with us, and it's typically on us to forward proposals or requests to other factions, or even make contact in the first place. The other major independent players throughout this part of the Periphery - Detroit, Rockawellawan and Fronc - for example probably should've contacted us in order to sound us out about our intentions, capabilities, etc. shortly after our existence became public, but especially so after Portland and Independence joined us.
Similarly, other periphery nations in general - the Marian Hegemony, Lothian League, Niops Association, Illyrian Palatinate, Mica Majority, Outworlds Alliance, etc - also seem content to just ignore our existence.
It's probably a lot less work for the GM than constantly having to consider how those various powers might react to our various actions or what they might try to gain from us, but it also makes the other nations look a bit like, well, the NPCs from video games, I'm sorry to say.
