10 Insanely Long Open-World Games That ARE Worth Finishing

At first blush, Subnautica, once it gets going, appears to be a fun riff on Minecraft, but underwater instead of on a randomly generated patch of dirt. Fun as that sounds, you may then labor under the impression that it will be like Minecraft in structure as well... that is, it doesn't actually have an ending.

And you would be wrong about this! Subnautica does indeed have a goal to work towards - that being of course getting off this giant ball of very dangerous water.

Knowing there's an ending to work towards gives Subnautica's massive world much-needed structure. There are places you can't go until much later, and obstacles you cannot overcome until you have crafted the proper tool for the job. Along the way, you build your ideal Minecraft-style underwater base as your need for resources increases, organically driving you to build and adapt according to your needs. The ending itself, while bittersweet since it ends the only way a "stranded" type story like this can end (i.e. leaving the planet and thus all your cool stuff), still feels so fulfilling after all the effort you put in to get there.

Subnautica is a big game featuring a very big, very dangerous ocean, but It is absolutely worth finishing to see all your efforts come to fruition.
