Yeah. The environment is much more dangerous and resources are much scarcer, to the point that you have to actually make tactical decisions about how you use them. Get careless, or make the wrong choice, and you will die.
Pre-patch, you never had to worry about your life support or hazard protection or shields or launch thrusters, because you were never more than five feet away from everything you needed to keep them going. They were just these annoying things that made you stop whatever you were doing every five minutes to refuel them. I'd mostly just wander aimlessly on the planets trying to find and scan all the animals, or looking for good screenshots.
Now, I'm constantly keeping an eye on things like, how far am I from my ship? How much further can I go, before I won't have time to make it back before I freeze to death? What if an acid rainstorm pops up while I'm out here, are there any caves I can run to for shelter? Are there predators in those caves? Is it worth spending the fuel I need for life support to jetpack across this canyon to get the mineral deposit? What if I don't make it, can I survive the fall? Did that sentinel see me chop down those trees? He did. ####. ####. Should I find someplace to hide? Can I make it back to the ship? How far was I from my ship, again?
