I loved Mark of Chaos when it was relesed and I love it even more today on GOG. Borderline genius combination of game mechanics from games like Spellforce, Warcraft 3 and Total War in to a RTS RPG in the Warhammer Fantasy Battle world. What's not to love! People are complaining that it's not running on Windows 10, which is strange because on my Win10 PC everything is running smooth. Bay it, PLAY IT!
