"The main issue is the game's incongruous mix of low-brow presentation and incredibly clever action; each seems to betray the other, but you won't have long to analyze that rift."

DID YOU KNOW?

Incongruous" is a spin-off of its antonym, "congruous," which means "in agreement, harmony, or correspondence." Etymologists are in agreement about the origin of both words; they trace to the Latin verb "congruere," which means "to come together" or "to agree." The dates of the words' first uses in English match up pretty well, too. The first known use of "congruous" dates from 1599, and the earliest print appearance of "incongruous" dates from 1611.
