Noticed there's no Terraria thread, so decided to make one.
A recently released game from a small independent studio similar to Minecraft survival crossed with retro Zelda games, with the focus more on action then creation, although it still has plenty of creative potential. It's available for £6 ($10) on Steam, or as a 4-pack for £18, and has been one of the most played games on Steam since it's launch on 16th May. It features support for both single player and multiplayer co-op or PvP, which characters being fully transferable between servers, and servers holding up to 8 players at a time with full drop-in drop-out functionality. The game features progression from wood based items through to various grades of metals up to space age technology such as 'phaseblades' (lightsabers) and laser pistols.
I'll post the wiki descriptions here to give you a better idea of what exactly it is. The developer Q&A/FAQ can be found here.
Below is the trailer:
If you want to see more gameplay, but in co-op, two of the developers (almost half the team) have made a series of "Let's Play" videos on youtube.
I highly recommend this game, it's exclusive to Steam at the moment and can be bought for either £6, or £18 for a 4-pack. Clicky.

Wikipedia said:Terraria is noted for its similarity to Minecraft and classic Square Enix titles such as Final Fantasy. Basic gameplay features day/night cycles, aggressive nocturnal attackers, world-building elements and character advancement based on increases to health/mana and equipment found while exploring. The game has a graphical anime style reminiscent to the 16-bit sprites found in video games released for the SNES.
Beyond basic gameplay features, Terraria has several elements not present in the games it takes its inspiration from. By completing specific goals, players can attract NPC merchants to occupy structures they have built, and may then buy equipment with coins gained from defeating monsters.
Random events may also occur in the course of play, such as the Blood Moon, which increases the number of monsters out at night and allows zombies to open doors to the players home, and the goblin invasion, which sends a goblin army to attack player structures. Events can also be caused by destroying orbs in evil map areas and using items near altars.
Players may also summon powerful boss monsters such as the Eye of Cthulu and Skeletron, who drop rare magic items and crafting materials. The developers plan to offer free content updates in the future.
