I'm going to ignore all the talk related to the investment pool thing. Plenty of other threads to discuss it.
Also, I find it interesting that so many people disagree with me, yet nobody seems to be defending Vicy2's system. I can only assume that people want an innovative new system, they just disagree with my proposal. I will need to think of a better idea.
And is the only alternative this industry can come up with is "selecting a research focus to get a random technology"?
If the spirit of the nation wants to be all in on Impressionism or Ideological Thought, so be it.
But how is the government enslaving the minds of our nation's philosophers and artists EUnderhill? Hooooow?
A better solution is player have direct control of research plans in military techs and business regulations, with uncontrollable civil techs development as prerequisite/research time reduction for them.
An interesting idea, but I worry that this will give the player too little control over research. Maybe have military techs act as prerequisites to civil techs?
I think overall the research should be a combination of drift and drive mechanics. The player should be able to steer their country's research, but not without outside forces drifting it too. Innovations should spread within markets, over trade routes, and through warfare among other ways.
This is basically what the devs seem to be planning, init? At least, that's what I can glean from the "Everything We Know" post.
What I wanted for Imperator was an "Eureka" based system that when something specific happens, things will unlock and then slowly things start to get adopted.
Another great variant on research is the Shadow Empire tech system but that game really surpasses any other 4x in the market right now.
What is the Shadow Empire system?
In my opinion, the best approach would be to have research as a cumulative result of:
the strength or funding of related industries or government branches
government research grants or subsidies
spread from previous discoverers through trade networks and non-hostile neighbors
general level of education in your society
clerics and teachers (the latter after implementing mandatory public education)
Most of those could be manipulated to varying degrees by the player, but each of them would have additional effects and complications, so you couldn't just max out all of your research inputs without causing other issues, yet many of those would steadily increase through the normal course of economic and social development.
Each field could gain a few points per day from each of those sources, some of them fluctuating randomly, others fairly stable over time, with no visible research bar to tell you exactly WHEN the research would complete. All you'd know is that something in field X is being researched, and at some time in the future, depending on the things that would realistically influence it, it would be discovered, and you would find out what exactly out of several possibilities had been discovered, rather than a predictable totally linear progression. At most, putting the technical field in a color to represent its "approximate" level of development of the next tech could be implemented, so a red tech would be practically unresearched, yellow meaning well on the way but far from done, and green would indicate nearing completion.
I consider that an improvement over 100% control or totally random development.
Not showing the exact progression is weird, but otherwise, I agree 100%. The most important thing is that the individual industries need to be the main source of research. That way only your major industries can be at the cutting edge.
Of course, governments did became major players in research during the 20th century, with the US funding the research of techniques to increase agriculture yields for example.
In addition to the industries should be your philosophers, artists, and scientists. You should be able to give government support to a particular school and style in order to gain its benefits, with the risk of that particular style going out of fashion. Art, in particular, should be heavily reliant on patronage, at least until the late 19th century, where the rise of independent art galleries allowed artists to go outside the academy system, which gave rise to Modern Art.
