Majority or plurality?

Majority means more than everyone else (combined).

Plurality means more than any one else (more than any one single other).

If Alice has four, Bob three, and Carol three, that means Alice has the plurality. No one has the majority.

If Alice has six, Bob two, and Carol two, that means Alice has both the majority and the plurality.

Many board games (and other systems) care about plurality rather than about majority.
