As far as I understand the adventure builder, yes they could. From what we've been told you can create adventure triggers on pretty much anything, time based, encountering something or someone, etc. No reason why certain planets can't have an adventure trigger based on encountering a 2010 monolith or driving to the top of the tallest mountain (invisible proximity trigger at that mountain peak) etc.

I'm really looking forward to seeing adventure construction in action and getting my teeth into it.

Star Control 2's lander looked like a generic sci-fi shuttle too.

Also the SC:O lander needs to be able to hover to be able to dodge in any direction while fighting creatures down there and have that boost ability to leap over terrain.

The game Homeworld proves that polygonal does not have to be ugly.  I think the lander looks fine even though it's cargo bay looks rather small compared to what I assume is a human-sized cockpit.  Star Control 2's lander had a small cargo bay too.

I take it back. It doesn't look generic. It looks plain, therefore boring in design. The best part of its design are animated engine parts.

I, too, think the lander needs an overhaul in the looks department. It should be striking, and stand out a LOT (since you'll be using the lander, arguably 2nd most in the game, besides capital ship). Something like Subnautica comes to mind. Every single ship in that had this incredibly unique look, unlike any other game I've played. White. Bulbous. Ultrasleek. Like it was made by a designer, rather than an engineer. 

Not to say you should copy the look - just make sure it doesn't look like every other ship that's ever existed in the scifi space.

Another recent impeccable vehicle design is in Surviving Mars. The rockets sort of resemble killer whales - so it successfully throws out your previous knowledge of what a ship should look like, and replaces it with this fun, interesting new design you've never seen before.

I mean, even the original lander! Lime green???? It definitely stuck with you. 

The flagship is your guys' absolutely BEST design decision. I love it to death. The rotating rings give it this incredible look that no one will ever forget. The lander just could use some tweaking to make it stand out, and maybe a paintjob. I'm not against lime-green

I had forgotten that gameplay teaser. Was that just a rendered animation then? Because the planet looked really good.

The trees and mountain/rocks looked really nice. Lighting needed work (it's better now), but those features and the look of the canyon etc were awesome.

That's the idea.

I think Lander should be more aerodynamic looking. More polygons, smoother curves. I just absolutely dislike it's hexagonal head/cabin.

reminds me of the graphics of this era:
