Re-Logic actually hit the milestone before the end of 2016, the company said. Terraria debuted in May 2011 on Windows PC, meaning that it took about five and a half years for the game to reach the 20 million mark. According to Re-Logic, 8.5 million of those 20 million copies were sold in the 18-month period between June 2015 — the release of the version 1.3 update, a significant one — and the end of 2016.
“The entire team would like to say a massive THANK YOU to all of you for making all of this possible,” Re-Logic said in a news release. “It has been a pleasure to have all of you along on the journey thus far, and we are really looking forward to continuing down that path. Terraria is a game — and a franchise — that has so much life left in it, and we cannot wait to share those plans with you in the months and years to come.”
Re-Logic also thanked its partners at publisher 505 Games, which helped bring Terraria to consoles and mobile devices. Engine Software handled the console ports, while Codeglue developed the mobile versions. Since its PC launch, Terraria has been ported to every platform under the sun: PlayStation 3, Xbox 360, PlayStation Vita, iOS, Android, Amazon Fire TV, Windows Phone, PlayStation 4, Xbox One, Mac, Linux, Nintendo 3DS and Wii U.
As for the future of Terraria, Re-Logic said the console version of the 1.3 update is “just around the corner,” to be followed “right behind that” by the mobile version. Re-Logic also plans to provide a status update soon on the long-in-development project known as Terraria: Otherworld, which the studio and Engine Software announced two years ago today. The most recent progress update came in July 2016, when Re-Logic said it had realized at the start of the year that Otherworld needed “quite a bit of work — and even a good bit of rework — in a number of areas.”
