The box art for Karnaaj Rally was criticized by many video game reviewers and publications. It was featured in 1UP.com's feature titled "Hey Covers... You Suck!" in which it is described as "..the world's ugliest man jump[ing] in front of the camera."[11] IGN's review of the game, although very positive, states that it is "hard to ignore the crappy name and awful package design" and advises readers to "Never judge a book by its cover."[8][12]
Seanbaby was criticized by readers when, in the June 2003 issue of Electronic Gaming Monthly (issue 167), he reviewed the game based solely on the cover without having played the game.[13] He later played it and reviewed it with "it wasn't as bad as it looked like it'd be" in response to the criticism.[13]
