Procedural generation is an incredible tool in video game programming that keeps titles fresh, with newly generated worlds making games still feel new and hard to predict whether you've been playing a game for six hours or six hundred.
While Minecraft 's procedurally-generated elements have given it a high profile, many other games use procedural generation to stunning effect. These games are fantastic examples of this mechanic.
10 Spelunky
One of the most acclaimed roguelikes of all time, Spelunky's replay value and longevity come not just from its procedurally generated caves, but how the other elements within the areas, when arranged in unpredictable ways, interact with each other.
From wandering cavemen to the strange behavior of how lava flows, Spelunky is full of unique variables that react in incredibly unexpected ways every time you start a new run. Players can pour dozens of hours into exploring the game's endlessly shifting levels and still find completely new items, areas, and environmental factors.
9 No Man's Sky
Hello Games' space exploration game is full of procedurally generated worlds in a vast galaxy ready for you to explore. The vast amount of real estate to discover gives this game an enormous amount of replay value, especially after the numerous patches, updates, and expansions No Man's Sky has received since its initial tepid release in 2016.
Hello Games has put in the work to make No Man's Sky every bit as vibrant and expansive as they initially promised. The deep space exploration/survival game is now bursting with content and mysteries around every corner.
8 Deep Rock Galactic
Last year's multiplayer hit Deep Rock Galactic lets players form groups of four as they explore procedurally generated space caves to recover treasure. What sets Deep Rock Galactic apart from other online co-op first person shooters is that Deep Rock Galactic's procedurally generated caves are completely destructible.
This makes environmental destruction a key feature, adding an extra layer of strategy and planning, or another layer of surprise for players who are less prone to planning. With its wide range of objectives, environments, and enemy types, Deep Rock Galactic knows how to keep missions feeling fresh.
7 Enter The Gungeon
Enter The Gungeon plays with a lot of distinct gaming flavors. The game is a bullet hell roguelite, wherein players drop into the titular 'Gungeon' (gun dungeon) and wade through a mountain of bullet-spraying enemies in search of a fabled time machine somewhere within the Gungeon's chambers.
Using one of four main characters, players will use scores of unique weapons as they try to traverse the constantly-changing territory of the Gungeon. The fast, frenetic pace of the game's combat means that multiple runs can come and go in no time at all.
6 Proteus
A much more mellow, low-stress endeavor than the other entries on the list, Proteus takes place on a procedurally generated, minimalist island. There isn't much more to the game than that: players just walk around their respective soothing, picturesque islands, appreciating the nature around them.
The game's soundtrack grows more active when a player nears a tree, animal, or body of water, and quiets the further away a player moves. Little touches like this make the procedurally generated islands of Proteus feel alive and real.
5 Dwarf Fortress
Dwarf Fortress procedurally generates its elements on a scale so grand that it can be dizzying. Before players can begin to get into the bulk of the gaming — managing a simulation of dwarves constructing a fortress — the game must first procedurally generate the game's world, its geography, and even its own history, complete with past empires, governments, nations, and even mythologies and literature.
Beyond that, the game also procedurally generates all the different obstacles and interruptions your dwarf colony might face. This depth of features is even more impressive considering the game first came out in 2006.
4 The Binding of Isaac
One of the first roguelites to acquire a serious mainstream following, The Binding of Isaac sees players controlling poor terrified child Isaac as he fights his way through the hellish and macabre layers of his basement.
The level layout, enemy distribution, and even the bosses the player encounters are all procedurally generated, and all uniquely terrifying and grotesque in their own way. What's especially impressive about The Binding of Isaac is how all of these disparate elements all feel so united in their constant creepiness.
3 Don't Starve
Don't Starve is, as the title would imply, a survival game where you do your best to stay alive in a dark, threatening world with a distinctly Tim Burton-esque art style. The game's world features procedurally generated geography, enemies, and a day-night cycle that throws further variables into the mix.
A co-op version, aptly titled Don't Starve Together, allows up to six players to collaborate in farming resources and building up defenses, letting friends work together to run through the game's harsh world.
2 Into The Breach
Into The Breach casts players as teams of mech pilots, staving off a world-threatening invasion of giant insectoid aliens. Each map is procedurally generated, mixing different layouts, enemy types, mission objectives, and bonus goals across the game's five separate biomes.
The game is brutally difficult, but it offsets this challenge by telegraphing all of its information to the player at all times. Enemy moves and attacks are always broadcast at least one turn in advance, which means everything a player needs to know to succeed is right in front of them, and if they fail, then it just means they weren't paying attention. This perfect information makes it very appealing to roll the dice on one more round, again and again.
1 Invisible, Inc.
Invisible, Inc., like many other games on this list, is a roguelite game that uses its procedurally generated maps and enemy arrangement to keep gameplay fresh and surprising across multiple runs.
Invisible, Inc. is unique, however, in being a turn-base tactical stealth game. Players are expected to tread carefully and thoughtfully as they try to pull off elaborate missions, using unique character skills and actions to make the most of whatever situation they're dropped into.
