When wondering what could possibly go wrong, it will probably mean a lot. Regular players Daniel "DanQ" Quick, "Makahlua", Scott "AlphaShard" Dirk and "UberMarklar" are accompanied by fellow co-operative Civilization V multiplayer players in the first TurnCast (TC) special entitled "The Great Mistakes". With a runtime of 41m45s, it contains snippets of the weekly gaming group's first foray into Civilization: Beyond Earth just the day after its worldwide commercial release.

TurnCast is the third spin-off of the Civ strategy-centric PolyCast on which Quick and Makahlua serve as regular co-hosts; the modding-centric ModCast was the first, and the console-centric RevCast the second, such spin-off. The fourth spin-off, SCivCast, covers Civ on social media.
