Don't Starve vs Fallout 4
Don't Starve
Don't Starve is a pretty dreary and dark survival game set in a rich world filled with plenty of animals/game to hunt, monsters to kill, and resources to gather. With a gothic-like theme, the game's best feature is perhaps the way it hands the reins to its players and let these players decide what sort of survival game they'd want to play and how difficult will the game be. You can literally customize everything in the world you'll be playing in, ranging from the weather, how frequent lightning strikes, how long a season lasts, how much resources are spawned and many more.The game also has a very nice selection of characters that you can gradually unlock as you play the game. Each character will even have their own specialty that you can then make use of when the situation calls for it.
Don't Starve is a survival game that's as punishing as it is vicious. Expect to die a lot in the game and turn all those deaths into useful lessons that you can then build upon. If you fancy surviving with your friends in tow, then you might want to get the multiplayer version of the game, Don't Starve Together, instead.
Fallout 4
Fallout 4 is the latest installment of the highly-acclaimed game franchise, Fallout. This time around, the developers went above and beyond, and completely revamped the rather outdated V.A.T.S. and turn it into a slow-motion-based aiming system rather than outright pausing the game mid-combat. The game has a massive graphics and sound overhaul as well. The visuals are a lot better than before and the devs added in something that was previously unprecedented - voice acting for the main character. The companions play their roles a bit better as well but they still tend to glitch out, or in some cases, disappear altogether. Thankfully, for PC gamers, you can use the command console to bring them back.In addition to its usual (and still epic) open world plus complete freedom features, this game also has a main storyline that forces you to pick a side in a war between factions, the Institute, the Brotherhood and the Railroad (the Minutemen are somewhat neutral in this game). However, the cream of the crop of this game is its sandbox aspect. In this game, even the junk items have their uses as you can use them to craft or modify your weapons, but also to build bases for settlers to inhabit and also a few extra places for you to stash some supplies in addition to your home in Diamond City.
Fallout 4 may have been ranked down on Steam due to Bethesda's decision to make paid mods, but the game itself is still a pretty good sequel for its combat system alone even if you don't like the storyline as much.
