By the by, just so it's clear - a single planet that you go from sky to ground in is not planetary procedural generation, that is simple a single planet possibly ProcGend but could very well have been done by hand and claimed to be ProcGen. ProcGen is taking this build mechanic and pumping out dozens, hundreds, thousands, or millions+ like E : D and NMS, and then showing the results with at least going across a few planets and moons. NOT what was shown at Gamescom, that doesn't prove crap, that is a SINGLE planet... possibly planetoid... that could have been done by hand and then claimed to be ProcGen. If it was ProcGen and working well - they'd have at least a handful to show that they could fly around, and maybe even land on.
