Every copy of Simpleplanes is personalized. Jundroo's experimental AI adapts and subtly creates a slightly altered version of the game tailored specifically for you, appealing to you subconsciously in ways you don't even notice, as well as attempting to mess with you and study how you react to it. Have you ever played someone else's copy of Simpleplanes? Have you ever felt like something was just a little bit off? That's why. That's how. This is much more than just simple experimentation with procedural generation, however. There are many layers to this, and some of them are more epic and badass than others. Simpleplanes is, at its core, an awesome and holy work of human creation.
