Pros
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.
