2. CIVILIZATION IV
The leap between Civilization IV and V is perhaps the biggest in series history, and there’s a very good reason for that: because Civ IV took everything about the series’ original vision—the one based on a grid and unit stacks—and pretty much perfected it.
Even the little touches in Civ IV, the icing on the cake, were the best. Think the Grammy award-winning theme song, or Leonard Nimoy’s narration, which peaks with his amazing “pig iron” intro.
