I loved terraria ever since it came out and also had a demo, and I hoped I get the game one day. The 1.2 version wasn't very good.The 1.3 version changed everything, the only it really need now is like a Facebook save or something, because if the person uninstalls the game and gets it back you loose all progress, but the glitch was fixed, now if you close the game or if it crashes, the game won't automatically delete a character or a world on it's on. I believe it's a well made progress/update.
