VGW: “If it ain’t broke, don’t fix it.” This time-honored cliché is the guiding principle behind THQ and Jellyvision’s You Don’t Know Jack (YDKJ), the irreverent and often hilarious trivia party game. In fact, YDKJ’s classic gameplay hasn’t changed much since 1995. Is the game’s strict adherence to its roots just lazy development, or is the zany and humorous format future-proof? 5/5
