I don't usually get active in game forums but this game has struck a chord with me and I thought I say a little about my experience so far. So, I have played both campaigns all the way through 1930, on normal and hard. I have also did it with auto generated fleets and custom fleets. Understanding that this first iteration of the campaign is just a barebones starting point I don't have too much to complain about knowing that or its already been mentioned(wonky ai). But I do wish for ongoing war, im sure you already know that 1920,1930 campaigns still end quite quickly which makes research feel next to useless to fund. I think the option to continue the campaign with Periods of peace time so the AI can regroup and Tech can actually be developed. Obviously there would be a lot of balance issues, for example, I'm sure removing the option to take land would be necessary to not permanently gimp the AI or give them a boost in research to help keep up. sometimes TR losses feel a bit aggressive also I do think TR losses should be in more of the players control with the convoy missions and I also agree that if AI is going to run they shouldn't engage to begin with, unless being ambushed which should then start at a closer range. last thing for now, the 1920,1930 should have battles spaced out a bit more with time or give the option to withdrawal if possible sometimes the economy gets absolutely wrecked because there was 6 battles in 2 months and half my fleet is in repairs. and even with minor damage the repair cost still seems a bit much.
Welp off to work. kind of rushed the whole thing but hoping my input helps at all.
