Introduction:
Terraria is a 2D sandbox game with elements of action, mystery and adventure set in a beautifully pixelated world of flying eyeballs and various biomes like hell. With the choice to build, mine, fish, explore, fight and ride unicorns, how you play the game is really up to you.

Pros:
-Customisable characters with cloud support.
-Dozens of weapons, armour, equipment, tools and consumables to choose from.
-Various mounts and pets to choose from.
-Multiple biomes with their own unique inhabitants, resource and behaviour.
-Over ten bosses that provide a challenge for combat lovers.
-Interesting NPCs who appreciate your horrible houses.
-More than one way to play the game (such as fishing, mining and dying).
-Hundreds of craft-able items and dozens of blocks.

Cons:
-Very time-consuming (although some see this as a good thing).

Overall:
Terraria is not a rip-off of Minecraft, but is actually a phenomenal game packed with fun and a lot of content. It is definitely worth its price and twice the fun when played with a friend. Even after beating the final boss, there are still lots to explore, discover and achieve in this wonderfully made game. I personally rate this game a 9/10. :)
