There should be an expansion, leader option, or scenario that applies some Marvel mythos to the Civilization 5 game.
There’s a couple ways you could approach this. I’m going to use the movie because we happen to be re-watching it right now.
Leader option: Director Fury (alternate for America obviously)
Great People (would be more interesting and you’d also have different spies)
Bruce Banner = great scientist
Tony Stark = great engineer
Black Widow = spy (obviously)
Hawkeye = ????
Captain America = great general (duh!) – benefits provided regardless of where unit is stationed
Agent Coulson = ?????
Erik Selveg = great scientist
Jane Foster = great scientist
Thor = great general
Loki = ????
Pepper Pots = great merchant ????? (Steve Jobs is considered a merchant)
Stark Expo: hosted by whoever reaches Information Age first (whoever hosts it also gets a research bonus for x+y turns besides the tourism bonus for y turns)
Landmark for the battle of New York, can also find tech from the battle as artifacts or a one time research bonus – only after researching future tech
artifact: Coulson’s Captain America Trading Cards
artifact: Glowstick of Destiny
Stark Industries: replaces factory, also provides 1 science
schwarma stand: 1 food, 1 happiness
Avengers Tower: reduces enemy spy success (like Stark Tower but not)
Replace building a space craft with something ?????
This seems like a good start
