I do have two ideas for planets in the future that are much less straightforward than the ones we've seen so far. A primitive planet like Mhenga but untouched, and an advanced world that never took interest in leaving their home. The emphasis I have on these worlds is very clearly -you are the first outsider to find this planet-. Up until now we've been dealing with sloppy-seconds planets, nothing we can say we discovered ourselves.
This could be approached different ways depending on the character. On the primitive planet they might just go in guns blazing to try and get to the probe in the wilds of the primitive world. Another player might, in order to make the locals think they are just an unseen tribe, strips their gear and has the ship wait in orbit or such as they wander the planet entirely unarmed and naked, working their way up with sticks then spears and other such things. And yes, I hear you already, 'tech specialists get fucked'. But not quite, given time they might have the knowledge to use alloys on the planet to forge steel blades or armor to jump ahead of the locals. Meanwhile a mercenary will rely on brute strength and becoming the dominant species by shows of force or making crude explosives. A smuggler might take a stealthier or more charismatic stance and convince the locals to aid him. Limited content in every direction in these areas but each class would be more specialized towards the above.
For the advanced world one could approach it one of four ways in my mind. The probe is in a military base, that one, the tech is onpar if not further along than your own. Show them how it's done offworld and take what's yours! Another strategy is to BECOME the reptilians. Shoot yourself up with transformatives made by an interested party or calling in a favor, and just waltz in as a scientist or by otherwise gaining the people's trust. Strategy three would be strealth, talking going through the vents and snapping necks espionage. Fourth idea kinda plays off the second in a way? Basically you spur the people on into an uprising against the elite/the people not letting their people explore the stars, and in the chaos you snag the probe and go on your way.
