If you're getting tired of banning contraception all the time or holding inquisitions, then Tropico 4's upcoming expansion, Modern Times, could be exactly what your banana republic needs. Seeing as it'll include the ability to filter your citizens' internet access, you can even give it that "future Australia" feel, if you like.
The Cold War was a fun time, for sure, but you can't blame Kalypso for wanting to bring Tropico into the present. According to the developer, the expansion will come with 30 fresh structures to build, among them biofarms and skyscrapers. There's also ten new edicts, including one which will let you limit or outright block internet access.
Now that's modern.
Rounding out the added content is a 12-mission campaign, so you can try out all this fancy stuff outside the bounds of free play.
While not mentioned in the expansion's announcement, going by the video, it looks like you'll be able to get a space program off the ground, if mining asteroids sounds more exciting that cultivating the finest tobacco (not that you'll be able to mine asteroids).
That rocket staging platform looks awfully close to civilisation -- I don't know anyone who'd enjoy having massive chucks of ice from the liquid hydrogen tanks smashing through their roof. Just another day living under a dictatorship (and Saturn V), I guess.
