I find it very hard to believe that there are people living today who don’t know about Kingdom Hearts. Still, there must be somebody or else Square Enix wouldn’t have created an introduction video to the franchise.

In a trailer released today, Square Enix gives prospective new fans the rundown of what they can expect with this year’s release of Kingdom Hearts 1.5 ReMix. In short, it’s an unholy union between Disney and Final Fantasy that has somehow become one of the best selling RPG franchises in the world.

Kingdom Hearts HD 1.5 ReMix is a collection of the the first three games in the chronological timeline – Kingdom Hearts, Kingdom Hearts Re: Chain of Memories and Kingdom Hearts 358/2 Days. The first two are playable games while the latter just contains the cutscenes from the 2009 DS game.

Kingdom Hearts 1.5 HD ReMix launches September 10 exclusively for the PS3.
