Ice planet generation in the game, currently, is awesome. It could use a "smoothing" step in the algorithm to round off the odd flat tops that happen when a formation hits the generation ceiling, but other than that, it's just amazing. You can get everything from mountainous landscapes, to plains dotted with glowing ice pillars, to ice caves, lit from below with an eerie blue light from the ice crystals - and almost every possibility looks amazing.
However, for other types of planet, this just isn't so. For the other planet types, it seems that the only variation between planet segments is that some are more mountainous and/or have more caves and overhangs than others. Purple planets have variable tentacle density, but that doesn't make for too many different possibilities seeing as tentacles tend to all look about the same. At very best, you might get a segment with a large floating island, or a rather boring city or pyramid on a terran or desert planet.
...This should eventually be fixed. Terran planets should have different tree densities and average tree sizes, with the possibility to have a few massive trees spawn. They should also very rarely get small wooden huts on the surface or the occasional abandoned underground base with an Isanth (Or some other small ship) in it. Purple planets ought to sometimes get strange pods and blobby towers of tentacle stuff and ice crystal on the ground with varying densities. (Finally, an explanation as to why there's blobby purple stuff on the old pirate stations.) Desert planets could have occasional oases with pools of water and skinny trees, along with things like outcroppings of stone spires sometimes appearing. I don't really know what to do with red planets, but perhaps they could get occasional stone huts, black rock spires with crystal blocks embedded in them, craters, and (very occasionally) a mysterious-looking alien device made of standard armor and rammet crystal, which would have a loot chest in it..
