FSX/P3D. I am actually waiting and wondering if there are any other developers left out there that just might try and publish "The final release of 2014" Maybe... maybe not. But Iain has officially published final shots of Monument valley so maybe it's possible. Either way, release is just around the corner. While I am at it, OpenLC EU v1.10 has just been released along with Orbx Libs: 141228. More info via the source link below.
