Getting out of your ship... i.e. standing up, walking to the airlock, going down a ladder onto a Strange New World (tm)... that would have been thrilling for sure. It would have been an
obvious thing to do - minimum viable product you might say.
Not at launch though.
What we're apparently getting instead is teleportation to the planet surface, with an SRV on foot, so you can carry a big gun and shoot things. Woo.

So no, just not exciting as an explorer. Sorry.
Exploration hasn't changed significantly since launch. They have added the FSS (which I actually like) but that divides opinion shall we say.

You can shoot probes at planets, but then it took them >9 months to fix the truth table that says you've already scanned that planet... doesn't exactly inspire confidence. Beyond that, what has changed? We had exclusively beige planets for >2 years, they broke the lighting system, and now we are where we are. No cities, no life, no comets, no strange spatial anomalies... just an endless procession of staring at a star (with a galaxy the same colour behind it that you shouldn't even be able to see at all) and honking.
There is SO much more they could do with a bit of imagination and risk. I get they need to "fill the galaxy with things to do", but tiny Hello Games managed that superbly using entirely procgen, so they can't even use that as an excuse any more. The secret is out.
Odyssey is literally last chance saloon. And so far, I am filled with dread rather than excitement. That's not right, surely?
