These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: Hoo boy, where to start? Where to end? Uh...there's the first game's opening music, and then the Paradise Island opening music, and then Pirate Cove's opening music, and then that one song with the bongos and Irish flutes, and...you know what, let's just say every single song in the entire series and be done with it.
The soundtrack of Tropico 4 is even better although it may not be as catchy.
Ear Worm: Tropico 3 is rife with these. La Gata Loca is catchy in its odd, quirky way, whereas Verde Y Madure and Asi! Vamos! take the more jackhammer-inspired approach, and...heck, about two-thirds of Tropico 3's soundtrack qualify. Made about 10 times worse if you're not a Spanish speaker yourself.
Goddamn Bats: Thanks to how schools work in 4, forget about keeping the Nationalists happy. (Basically, they hate immigrants...but you often need to hire a foreign immigrant to teach at schools to get the ball rolling, so....)
The Nationalists usually don't get too obnoxious about immigrants unless you set your immigration office to an Open Door policy, in which case they will jump on you almost immediately after setting it to that work mode.
Magnificent Bastard: El Presidente certainly shows signs of this in campaign mode. In particular, there's the Isla Desconida mission in 4, where El Presidente gets the island accepted as a European colony, then starts a communist revolution against...himself. Led by himself. To install himself as the ruler. The soviet agent and Penultimo are both pretty confused by the end.
