This looks like a lot more fun than air hockey: Four players use joysticks to control tiny wireless robots in MaruBot Football League, where each of the little guys seems to have a personality. Their LED eyes indicate happiness after a goal is scored, or sadness after a loss. Aww.

The game’s makers also have a heart, claiming the MaruBot game inspires “cooperation and partnership, minimizing individualism, isolation, violence of online games.” If a four-player game sounds like too much togetherness for you, there’s also a two-player version. Now a big hit in Korea, the game could someday show up at an arcade near you.
