Tropico IV is my hint for you, It's a great city-builder,
instead of an adventure, but you will have lots of fun
with it. You're a dictator on a tropical island who
must try to keep his people happy by building the
things they need or (true to the word) be a real dictator
and be a harsh ruler.
The risk is than there might be a revolt.
But you'll have soldiers and the secret police!
(That might save you're career (and life!) or not ...
You'll have different tasks to fullfill
to win an assignment. You can regard an assignment
as a Chapter.
The series have been a big hit in Germany.
I had lots of fun with Tropico 3 and 4
(have 5 as well ...)
