Terrarria is on a few platforms, but I played it mostly on my Vita. Terrarria is kind of like Minecraft, only it's 2D, has a smaller emphasis on building, and a much broader range of objectives, items, enemies, and minerals.

You can dig up any piece of the landscape you come across, combine materials to create new objects, and build a variety of things based off of the materials you have. Unlike in Minecraft, there are a variety of Non-Playable Characters (NPCs) that you can interact with, including by buying and selling items. In order for NPCs to arrive you need to build them a house - or at least their own suitable room as part of a bigger house. 

Though the game is 2D there are actually 2 planes - the plane with the bricks and another plane with walls. So if you want to build a house you not only need to create two walls and a roof, you need to place walls in order to seal off your house.

There are a variety of tools of the trade, including axes, picks, swords, bows, magic spells, and even flamethrowers. In addition to various armor, you can also find other items which grant special abilities - such as a balloon to help you double jump and boots which help you to run fast. There are also boss monsters that give large rewards and can further your progress in the game. If you dig deep enough you may even find the Underworld, inhabited by the dreaded Wall of Flesh.

I really enjoy Terrarria and think that it is full of fun and adventure. If you like Minecraft then I think there is a pretty decent chance that you'll find something to love in Terrarria.
