Two teams faced off Saturday in Jane McGonigal and Ian Bogost's game, "Cruel 2 B Kind," one of several featured during the Come Out and Play street games festival in New York.
"Cruel 2 B Kind" teams send "kindness" text messages (such as "Have a spectacular day") to an opponent in the hope that the greeting matches the opponent's designated weakness. If there's a match, the message recipients are "assassinated" with kindness and must join the winning team in its quest for more kindness victims.
If there's no match, the targeted team responds by texting "You're too kind" to the attackers, and both teams move on.
