It seems there's no wiki entry for fantasy.
Wikipedia already has a solid paragraph on it:
The identifying traits of fantasy are the inclusion of fantastic elements in a self-coherent (internally consistent) setting, where inspiration from mythology and folklore remains a consistent theme.Within such a structure, any location of the fantastical element is possible: it may be hidden in, or leak into the apparently real world setting, it may draw the characters into a world with such elements, or it may occur entirely in a fantasy world setting, where such elements are part of the world.Essentially, fantasy follows rules of its own making, allowing magic and other fantastic devices to be used and still be internally cohesive.
Which seems like a padded way of saying that fantasy usually consists of an alternate universe similar to the real world,with creatures from folk-tales/legend and the prominence of some sort of magical/supernatural phenomena being a staple feature (elves,centaurs,fairies,dragons,ghosts,runes,spells etc.).
Prominent examples:
Lord of the Rings
The Elder Scrolls
World of Warcraft
Other:
Tag group:legendary creatures
The Legend of Zelda
Fire Emblem
Castlevania
Anyone care to agree upon a definition?
