This page explains the references to other series featured in a promotional image for the game Croc: Legend of the Gobbos, part of the Croc series. Referenced series are Tomb Raider, Mario and Crash Bandicoot.
September 29, 1997
A promotional image for the game Croc: Legend of the Gobbos featured the titular character near slightly modified versions of Crash Bandicoot's shoes, Mario's cap (featuring an 'N' instead of 'M') and Lara Croft's guns, while he's using a toothpick, suggesting he just ate the three characters.
The advertisement also cites three articles from gaming magazines that positively compared Croc to Tomb Raider, Mario and Crash Bandicoot games.
Croc's company Fox had no right over Eidos' Tomb Raider, Nintendo's Mario or Naughty Dog's Crash Bandicoot, in fact they only featured modified versions of those game's elements in its promotional image. The name of Lara Croft, Mario and Crash could be used by citing actual articles from gaming magazines, since that doesn't need any authorization.
