Pros
Pro Allows for freedom of expression for all ages, all at your own pacing
Terraria has all kinds of tools and materials you can use to build whatever you can imagine. From housing, to furniture, to weapons, to type 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 groups of friends allows for endless scenarios of building and destruction
Up to 8 players can join a shared Terraria world, including the worlds that are used in single-player mode. This allows for large co-op or PvP games. Build something big together, or destroy the other guy’s base. The scenarios are endless.
Pro Find servers, tutorials, and streams within minutes online
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 Contrasting a bright and happy atmosphere with suspenseful survival mechanics creates a unique sense of tension
Terraria uses a bright palette and arcadey action to bring a sense of fun to the game. The slow addition of survival mechanics over time brings a nice sense of contrast that makes the survival mechanics feel that much more tense.
