I've logged well over 100 hours since launch, and I'm immensely enjoying myself, despite some room for improvement IMHO.
The game sure has issues, but I have to say it's been a while since I've been pulled into a grand strategy game like this at launch.
There's lots of room for improvement, but big fixes I'd like to see to be implemented soon are:
- fixing circular trades
- making political management harder (currently it feels sometimes too easy to "play" IGs and strengthen/weakenthem through development and law changes)
- making the AI better at developing their tech, economy and resource extraction
- making the AI more proactive on standard settings (after helping Bavaria against their war against Germany in the 1840s
nothing else happened in Germany for the rest of the game - no diplo plays, no one trying to unify, no nothing - countries just sat there, doing their thing); I feel in late game the AI becomes much more conservative about going to war - which makes sense, as war will become more expensive, but near end game they seem barely interested in interaction with others (YMMV - that's my impression, anyways)
- making the AI smarter about when to get involved in diplo plays and when not and what to demand
Mid-term fixes I'd like to see:
- more data transparency and visibility
- making sure that historical outcomes happen a bit more often (American Civil War, Oregon, Alaska, German & Italian unifications with historical territories, a mechanic for ramping up chance of Great Wars later in game, Meiji restoration ...)
- slowing down the scramble for colonies and making colony grabbing more reasonable and rooted in national policies (US should be reluctant to take any colonies until their political landscape changes or dixie landowners take over; even then it should look more realistic - US taking colonies/puppets in the Americas first, before taking chunks of Africa; Russia seems eager to get into Africa early in my games)
- more interactive wars (setting strategic targets, strategy/tactics offering more options with more advanced armies, maybe requiring you to "test" new technologies before they actually give you a major edge - journal entries try something like that but it could be expanded)
- more complexity to wars instead of all or nothing struggles (colonial conflicts vs. territorial wars between great powers), a mechanic to escalate wars (i.e. pulling the US into WW1, or intervening as great power, maybe at the cost of influence/authority?).
- the AI becoming much better at fighting distant wars - I've noticed the AI sometimes sitting passively for years, when sending one invasion fleet would resolve the conflict quickly (I sometimes switch over to that country and send the fleet for them before switching back to my own country)
- some mechanic (besides violate sovereignty) to get to enemies you don't have direct land or sea access to (transit rights? might also work for trade?)
- making trade slightly more complex (e.g. adding shipping costs based on distance between capitals?)
Long term (DLCs?)
- more industries/economics; e.g. add museums and artists/archaeology, opera houses and prestigious composers, painters, writers, movie makers .... (that's more a personal wish, which is probably of interest for few people
However, having "national literature", "national museums", etc. were important for national identity for some countries of the era); tied into this - more "great people" outside of the interest groups, maybe - inventors, business tycoons ...
- based on that - make IGs more complex; instead of just the leaders, have 2 "influential people" behind them that are jockeying for leadership and try to pull the IGs in different directions and affecting them to a larger or smaller degree to model the infighting some of those groups saw and making them less monolithic
- more national flavor and events
- foreign investment and informal empire building
- MOAR of everything
