My estimate was about 03:30:00, i make a really good orc campain, 01:39:52! Its my pb on this one, but the human one has been terrible, some reset, i loose about 10 min i guess. Don't worry when screen get black at start of a new map, i just swip page of my note from my second screen.

Played on this version of dosbox: DOSBox_0.74+xBRZ_1.4+Save_States_Win32

No savestate used, only rebind key used. The game has be reshade.

Mod edit: Removed 17 seconds of switching time due to timing changes
