The Binding of Isaac
September 28, 2012
The Binding of Isaac features many gameplay elements inspired, or even directly taken from The Legend of Zelda. The game features an overhead view like Zelda, and the status bar on top of the screen is almost identical to the one in Zelda.
Many of the game's items are used exactly like items from the Zelda series, including hearts, bombs and keys, and there also are enemies behaving like Zelda enemies.
The game even features a direct reference to Zelda II: The Adventure of Link in a secret room accessed at random by using Telepills, where there's a figure saying "I AM ERROR", which is a quote from Zelda II.
The creators of The Binding of Isaac held no right over Nintendo's Zelda, but they only included minor references to the series.
