FSX/P3D. Thank goodness for ADX readers otherwise I could never keep up with everything on my own. I came across this Kolyma project back in April of 2015 [SEE HERE] and then proceed to completely forget about it. Thanks to Zachary as always for keeping up with it on all our behalf's. One thing I can say about Russian developers, they do not screw around when it comes to detail. Some of the best freeware and payware out there. Super impressive stuff. Well, they have been posting updates since that old post, and it's looking... well... see for yourself.
