Which arcade game includes a love meter?

The arcade game that most famously includes a "love meter" is Dance Dance Revolution (DDR).

While not explicitly called a "love meter," the game displays a "Couple Gauge" which increases as players successfully complete dance steps together. This gauge reflects how well the players are coordinating and working together, which can be interpreted as a measure of their "compatibility" or "love" for the game, at least within the context of DDR.

Other arcade games might feature similar mechanics, but DDR is the most prominent example with a clear visual representation of this concept.
