Yes, it is pretty cool. I've done a bunch of exobiology myself, and it really gives you a good reason to explore planets, and that's where you see the coolest sights (I think).I got it. I found three different piles of that and then three different plants so I got two full samples.
This is so freaking cool. But I really need a new GPU for this.
I've always enjoyed working on the surface of planets, even when it was just prospecting for minerals in the SRV. But for a long time there wasn't much else to do or see. For a short while there were "rescue downed pilots" missions where you had to go search for occupied escape pods and bring them back. I liked it because it gave me a reason to fly low and look around.
Now, exobiology does a much better job at giving me a reason to be down there. I always feel very immersed and in-tune when I'm roving a planet like that. It's one of my favorite activities.
The plant life is pretty varied, and there's a science-y vibe to it, what with all the plant types and what terrain they grow on and what star types they show up in and what sort of soil composition they like, etc. FDEV did a pretty good job with it all.
