Why nobody ever uses them I will never know, but I do know this. Lava is TECHNICALLY a light source. This means it's light can only travel so far. Think Minecraft. While Minecraft doesn't have the best 101 physics or philosophy, its pretty solid in terms of light. Light is a major factor in the game and can decide life or death at times. Each light source has a certain draw distance, and each block further from the light source, it gets dimmer and dimmer. So if you guys were to incorporate that logic without the unrealistic draw distance and light sources, it would give a more, realistic feel to the lava. Then again this IS a game about three bipedal animals and a crazy obese scientist so anything could happen, but like level design 101 says, floating platforms are the exception.

Oh and by the way, IS this seriously a topic? I mean come on. There are other major things to discuss besides light physics.
