Zenith: My Favorite Mechanism

About Zenith, from BoardGameGeek:

In the far-off future, the solar system is inhabited by 3 races: Humans, Robots, and Animods. Civilization runs off of Zenithium, a clean and renewable energy source, but coexistence is a struggle. Your goal: unite the planets to gain control of the senate! Players will struggle to gain Influence on the 5 planets: Mercury, Venus, Earth, Mars, and Jupiter. This Influence is represented by discs in different colors. In Zenith, there are 3 victory conditions: Absolute victory: Gain 3 Influence discs from the same planet. Democratic victory: Gain 4 Influence discs from strictly different planets. Popular victory: Gain 5 Influence discs (from any planets). The game ends immediately as soon as one player meets 1 of these three conditions. -description from the publisher
