In an interview on TechnologyTell, David Welch of 505 Games discusses some of the challenges and successes that the studio has encountered while bringing Terraria to the Xbox 360 and PlayStation 3.
Interestingly, some of the new content to be included in the console ports was directly inspired by tools and programs that the PC version's modding community produced. "The in-game world map in particular was very inspired by some of the existing tools," said Welch. "And our redesigned crafting system was approached with the philosophy that console players can’t easily access the online wikis the same way that PC players can."
Toward the end of the interview, Welch admits that the touch-screen interface of the PlayStation Vita "could be a very natural fit" for another port, and that the studio is "looking into it." While that is far from any sort of official confirmation, it's pleasing to hear about the possibility of Terraria reaching a wider audience.
