$14.99 for the complete edition
Pure Chess has already hit the Wii U and 3DS, but it's coming to the PS4 soon. VooFoo Studios released the game way back in 2012 on the PS3 and Vita, but has decided to start porting it to current systems, hence the new release date. It'll ring in at $7.99 for the basic version, or $14.99 for all the DLC.
Yes, there's DLC in a chess game.
