Terraria uses a bright color palette and an upbeat chiptune soundtrack to ease you into its world. However, once you start exploring and spend time in it you'll notice it's not as cozy as it first seemed to be. Blood Moons that rouse the dead from their graves. Goblin armies trying to destroy everything in their wake. Vast and dark cave systems, filled with odd creatures and various dangers. Ancient ruins, teeming with the restless dead and evil spirits. Pockets of decaying land, thriving with misshapen monstrosities. It's really fun to explore and discover something new about the world of Terraria.

Pros
Pro Teaches orbital dynamics & rocket design fundamentals in an accessible manner
The physics engine does a reasonably accurate job of replicating the fundamentals behind both orbital dynamics and rocket design, so by going through the tutorials and experimenting, you're actually learning some real rocket science.
Pro Tons of stuff to do
Build rockets, space planes, space stations, rovers, landers, probes. Explore planets, moons, capture asteroids, set up a communications network, colonize a planet, mine for resources and much more. It can even simulate our solar system.
Pro Huge modding scene
There's a plethora of mods available that can change every single aspect of the game.
Pro Excellent construction sandbox for building and launching rockets
KSP at its core is a rocket building and launching sandbox. When creating a rocket you can place engines, fuel cells, structural elements, and even parachutes, allowing you to build a rocket in any shape and size. The end result can even look like a giant doughnut, which might be difficult to get it into outer space. Even if you fail, the entirety of the process is really enjoyable.
Pro Motivates you to learn
Kerbal Space Program puts into perspective how amazing the advancement of the human race is. It inspires you to learn our history, how we got here, and what we can do proceed.
Pro In constant development
KSP is a shinning example of early release done right. The currently available game is fun to play, and the developers are constantly adding new major additions.
Pro Intriguing world
Terraria uses a bright color palette and an upbeat chiptune soundtrack to ease you into its world. However, once you start exploring and spend time in it you'll notice it's not as cozy as it first seemed to be. Blood Moons that rouse the dead from their graves. Goblin armies trying to destroy everything in their wake. Vast and dark cave systems, filled with odd creatures and various dangers. Ancient ruins, teeming with the restless dead and evil spirits. Pockets of decaying land, thriving with misshapen monstrosities. It's really fun to explore and discover something new about the world of Terraria.
Pro Allows for freedom of expression for all ages, all at your own pace
Terraria has all kinds of tools and materials you can use to build whatever you can imagine. From housing, to furniture, to weapons, to types of structure, the possibilities are almost endless. This is great for children who enjoy building and problem solving, and for adults who enjoy the same. It also makes for a great objective-less game, where you can do just about anything you want at your own pace.
Pro Playing with friends allows for endless scenarios
Up to 8 players can join any Terraria world. You can progress through the game normally, build a race course and compete in it, or split into factions and wage war against each other. The scenarios are endless, you just have to let loose your creativity.
Pro Lots of community servers, tutorials, and streams
Terraria has a large community of players on every platform including mobile, desktop, and console. Because of this, there are many servers to play on, as well as tutorials and Let's Plays. Finding content or help getting started is quite easy.
Pro Fun combat
It starts out simple, with you whacking away at slow moving zombies and flying eyes, gradually shifting to more fierce and fearsome enemies such as flying demons, agile lizardmen, and many more. To survive you'll have to be always on the move, dodge enemy attacks, and be accurate when you retaliate.
There are also plenty of weapons to choose from. Melee weapons such as swords, hammers, lances, and flails. Ranged weapons such as bows, crossbows, rifles, and miniguns. And various items that allow you to cast spells. Whatever you choose, it feels great to destroy hordes of enemies.
Cons
Con Some visuals are poorly done
While the rockets, buildings, and even the Kerbals look pretty good, the environments and particle effects are a bit lacking.
Con Steep learning curve
Kerbal Space Program is not really a pick up and play title. It can take hours just go grasp the basics and the game will keep throwing new concepts at you as you progress into space, even stuff like orbital dynamics. Because of this, it can easily take dozens of hours to truly master this game.
Con Progress can feel slow
Quite often you'll have to collect tons of materials to craft the necessary tools, equipment, and boss summoning items to advance. This can take a really long time, especially if you're unlucky with the items dropped by mobs.
Con Low replay value for those who play it as an adventure game
Terraria is a sandbox platform-adventure game, so it partly hinges on beating various bosses. If you play it purely for the sake of defeating all the bosses, you might have little else to do afterwards. Restarting the game won't be as enjoyable either because you'll already know what to expect, causing continued play without a new goal feel mundane or boring.
