Kingdom Hearts I & II

I've been spending some time over the past couple weeks enjoying the seminal (meaning industry-advancing or significant, not semen-related) Kingdom Hearts games for the Playstation 2.  While the gameplay is nothing new, and the story bounces from whimsically simple to the Square-Enix induced complexity of a theoretical equation, the real standout of the game is the sheer depth of intellectual property fed into the game from both Disney and Square-Enix.

Kingdom Hearts the first tells the story of Sora, Riku, and Kairi; happy-go-lucky youths who live on a small island and dream of exploring other worlds.  Their dream becomes reality when their world is "connected" to others through a menacing bad mojo known simply as "the darkness."  And this darkness also spawns monstrous concoctions known as Heartless, who errupt from a person whose heart fell to darkness.  Luckily, Sora is a chosen wielder of the Keyblade, a device that can destory Heartless and seal the doors between worlds.
