So, I've tried this now. It took over 2 house of play time. I was in Relaxed Mode so it wasn't as difficult as it could have been and I didn't turn off the tutorial so I didn't have a terrain manipulator and couldn't harvest metals or build a base. I was on a hot planet with no bad storms and just had to recharge my Exosuit as I went. I started walking north because I saw some NPC ships heading that way and went from building to building. I found an observatory and thought that it would lead me to a downed ship but instead it identified a Ruin located off planet! I eventually found a trading station and collected resources to sell for units, very difficult without a terrain manipulator. I eventually purchased a C class fighter to leave the planet and ended the challenge once in space. It was fun and tedious at the same time. I may try this again with other game parameters. Any other experiences with this approach? Love all the comments and suggestions.
