• Beautiful/stellar music, esp The Hallowed and Space
  
• Charming graphics/very colourful (makes you sit in awe of the world)
  
• Patch 1.3 added 800+ new items
  
• Good item tier and crafting system
  
• Allows for a lot of creativity
  
• High replay value
  
• 3 map size settings/huge top to bottom maps
  
• Variety of biomes
  
• Imaginative bosses (14-16 in total), invasions, and special events, e.g. Halloween and Christmas (which you can get early on if you manually alter your computer's time and date)
  
• Developers are a decent bunch of ducks, so support this [great] game!
  
• Welcoming community
  
• Now supports Steam servers

• Starting game can be somewhat slow
  
• Several achievements are bugged, e.g. heart breaker in multiplayer. May require a new world after a patch to recognise the achievements properly
  
• Switching between items [1-0] can be infuriating and often unresponsive
  
• Previous versions won't work well on newer patches, e.g. 1.2 worlds won't respond well to a 1.3 patch
  
• There's a lot of information to remember in this game, so you may have to refer to the Wiki a lot (can be - depending on the person)

I would definitely recommend this game, especially considering the £/$ per enjoyable hour model. It's also a game you can come back to over and over again, and one that's truly timeless, and can be played by all kinds of gamers.
