About the game:

- turn based single player strategy

- you are a dictator that rule a tiny country (island in the middle of nowhere)

- the country's main income is from plantations (coffee, bananas, cotton, etc), there are also plenty of rebels, factions that want to usurp the power and generally the country is highly unstable politically

My ideas (somewhat longish...):

- Banana Republic Directorate

- Banana Republic Sim

Don't use "banana republic" in the title - although there's little chance of somebody thinking it's a game about clothing stores, the company still might sue.

How about "Junta" or "Republic of Nowhere"

Make the title the name of the country you'll be ruling.

Look up names in different languages anglicized such as

Vidarr

which was an old Germanic diety whose name means ruler.

Vidarr, Vitharr.

Just an example.

President for life, El presidente, Rebel Republic

Make the title the name of the country you'll be ruling.

Look up names in different languages anglicized such as

Vidarr

Important note, the title needs to convey the meaning of "being a dictator" (or something similar), so people can notice it instantly (and buy the game because they always wanted to play as a dictator :D).

Maybe something like "Dictator of COUNTRYNAME"?

Wish I could say Tropico... but that's been used.

I would include any of these words:
Principality, Sovereignty,

"Dictatrouble" :)

"My People of IslandName", "Land of the Tyrant".

Put a picture of a mock-up Fidel Castro in the cover and-, wait, no, Tropico already did that.

Use a mock-up Hugo Chavez instead.

President for life

I like this one a lot.
