Old Chinese version

The old Chinese version (lit 旧国服版本) of Terraria was created in collaboration between 505Games, Pipeworks Studios, and iDreamsky Technology. It was the first attempt at bringing Terraria to the Chinese market. Development was headed by iDreamsky's in-house studio Ledu Games, largely based off of Desktop 1.3.0.7, with some 1.3.5.2 content as well. However, due to government regulations and differing consumer taste, many changes and additions were made to the game.

The game was "free to try", allowing players to play the game for a short amount of time, and then pay to unlock the full game when time ran out. In order to fit in more with the Chinese market, the game was treated as more of a service or a subscription than a game that one would own. As such, the game was highly internet-dependent. The service ran from early 2018 to June 9, 2020. It was shut down due to copyright expiration and disagreements between iDreamsky and 505 Games.
