It all started in 2009 or before, Redigit met with others to develop Super Mario Bros. X that is also called SMBX.
After the release of SMBX 1.3 Redigit and his team were without the site
http://www.supermariobrother.org, then in 2011 the company was named Re-Logic and was made official and released several versions of the game Terraria.
