Would you mind explaining to me what Tropico is?
I assumed both Tropico and Hidden Agenda were about running a country, staying in power as long as possible, fighting off or bribing off internal enemies, and (possibly?) improve the country you're running. If that is not the purpose of those games, then I'd wish to know what they are. [about aspirations or aspersions snipped] ...
There is a problem with the assumption. Consider the:
Definition of market niche: A small but profitable segment of a market suitable for focused attention by a marketer. They were intended for very different purpose niches, and came at different times in the development of computer games. Additionally,
"running a country, staying in power as long as possible, fighting off or bribing off internal enemies, and (possibly?) improve the country you're running" are NOT actually commonalities of the two games.
Hidden Agenda, along with
Junta and other games were sources for the 'PopTop' developers.
Tropico is a mixed genre PC game using a number of inspirations to create a game which uses a very elaborated NPC individuality format. The development team leader was no doubt using this game as a test for his concept for RRT3 which elaborated stations and train loads. (unfortunately "Trainz" hit the jackpot with model RR fans)
Hidden Agenda was developed as a "teaching tool" rather than an amusement game. The player is cast very specifically as a figurehead with some power, but limited by the members of the "junta" which control segments of the legislature. He has to select from among the members of the "junta" to form the executive government. He is "type cast" at the start so the student player can express a personal political opinion (yes, rather crude - but good for the computer era). Then the student player falls into a decision tree (based on three) which tests his ability to learn on his feet and reach his political goals while also reaching the game's goal. Oh? The game's goal for the player?
You inherit a true crisis. While the people are exhausted from the tumultuous insurrectionary period, the country is not devastated physically. Yet it will take at least three years, the Junta has declared, to bring the country back to some degree of normalcy. They have granted you the power to rule largely by decree, though it is understood that the other members of the Junta are your peers and will serve as spokesmen for the National Assembly. You will select from among them to form your cabinet and largely follow their advice. For the time being, you have the support of the Junta of the Insurrection, the Reconciliation Army, and the people. But as an old Spanish proverb says, "throw a bone to two friendly dogs and you have two enemies." The country waits to see what you will do with their support—while it lasts. You are not anything like the "dictator" player of "Tropico" who is not beholden to anyone, but may be turned out by several means by the NPCs.
A
Junta game is multiplayer which involves the players compeating to be the "dictator" as head of the
junta with lying, cheating, etc. with the country as a mere background. It may have inspired the
"factions" in Tropico.
Tropico seems to be a somewhat different mix of things for the player to do. I think it is unique in its use of complex NPCs. The story line you suggest seems a little thin.
T4 seems to claim to leap beyond the 1950's Cold War into the current day of the 21st Century.
IMHO they did a piss poor job of it.
