Unfortunately, I don't have any screenshots.

I want to say they were both smallish worlds part of some alien worlds series. Had to diy lot placement. The tron color scheme one was pretty cool since the ground was all black everywhere with just slight bits of neon here and there, which make it useful imo for a far future sci fi castaway sort deal.

The other world was earthen hued mountains, the whole world was scary yet pretty jagged peaks that made travel difficult.

I remember seeing them on Tumblr probably around 10 years ago, also on 3dmgame about 5. They were made by the same author if that helps at all. On 3dmgame people complained how the worlds were only good for screenshots but not really for playing since no lots were placed and there were limited to no roads, in the case of the mountainous world the wild terrain didn't help for standard play, but for an alien caveman castaway it was awesome.

Beautiful worlds! But not quite what I'm looking for... I've made a quick recreation in paint of what the worlds looked like, they were incredibly simplistic. Its been so many years so it's a fool's errand to hunt them down, I absolutely love Katy's suggestions might end up going with those for my sci fi castaway game.

In the first world it was all black with neon light for any terrain features. The second world was all spikey cliffs, my quick little mspaint doesn't capture it provoked both anxiety and wonder. I put a lil stick figure to sort of get a sense of no easy terrain.
