I have always known what Kingdom Hearts was since the first commercal for it. But I didn't really get into it when I saw Birth by sleep. Birth by sleep was the very first kingdom hearts game i ever played. Got the game of Christmas 2010. Then when my birthday came up my dad bought me a ps2, got all the games for that platform and soon after i got all the ds games and i have dream drop distance now..soooo..for me its been about 2 years playing it.
