I still disagree. Truly iconic leaders, who should be prioritized in the game, have had cities, nations, even entire eras named after them. Think of Elizabeth, Victoria, Napoleon, Stalin, Genghis-Khan etc. Their names alone evoke the full sweep buildings, technologies, government types, values or political events that defined their time.
To me, leaders are what give a single civilization its internal diversity. Take Peter the Great and Stalin. Both could represent Russia, yet they relates to vastly different eras, ideologies, and leadership styles. Same civilization, but radically different vibe.
