well i colonized all the different types of planets with the exception of a glitchy, extra exotic planet that would not let me land. i built all stations and at least two trucks on each. Since the trading platform removed the need for actually mining, i just traded coal, titanium, and materials i got from other planets for resources i needed at the time. I guess i could set up more habitats to colonize more of the planets, but that would be terribly boring and uneccessary since i no longer need research orbs or in that case anything that the planet has to offer. Even though the replayability is harshly limited, i still do play with my friends when im bored and do plan to play when the game is updated.
