Dueling Shows: With Wheel of Fortune; except that Definition was not shopping-based (the Ceramic Dalmatian would have been a relatively decent prize under this show's conditions), and used the tried and true "celebrities and civilians" structure for most of its run.
Hey, It's That Guy!: Jim Perry would become quite well known as a game show host on both sides of the border.
No Budget: The show was ridiculed by outsiders (well, specifically, Americans, given that cities like Buffalo could pick up stations from Toronto and the surrounding area) for how cheap the prizes were. Seriously, the consolation prize for losing the Bonus Round was $10. Only if you made it to the yearly Tournament Of Champions could you have an opportunity to win something half-decent, such as a car or trip.
While most Canadian game shows suffered from similar budget issues, Definition's case became even more ironic when Jim Perry, around the same time, ended up hosting some of the United States' richest daytime game shows. (i.e. Card Sharks and Sale Of The Century)
