Is Below Zero worthwhile for someone that was enthralled with the early and mid game of Subnautica but totally got bored in the late game?
Later vehicles were more trouble than they were worth (yet utterly necessary), there became less and less direction on where to go (seriously, finding the lava fields without using the internet seems unlikely. Obviously people did it, but it was well hidden and I found nothing directing me there), and it started to feel tedious. Getting places wasn't easy. Getting resources wasn't easy. Your new vehicles had a LOT of resources tied up in them and didn't feel worth risking, since resources didn't renew and rebuilding one of them, with the mods, would be an arduous task.
But I loved the initial exploration, finding new worlds, new parts, new base rooms, new creatures, etc. It was only going into the very end that it started to feel like I'd be going somewhere more trouble than it was worth. (I think part of it is that I never fully learned the mechanics of what can kill you, because losing a vehicle once taught me mostly to avoid, and therefore I had no clue if something would follow me to the heavens, or follow me 10 feet.)
