The RTS genere peaked in the 1998-2002 golden age period with titles such as Starcraft, Warcraft 3, Tiberium Sun, Age of Empires 2, and Total Annihilation. And then the genre collapsed.

The debate regarding the causes of the collapse of RTS continues to this day. At the risk of going out on a limb, one big reason for the collapse of the genre was that its micro-intensiveness was dull and rote.

And that's why in the early 2000's, the RTS genre innovated in the direction of less micro and more strategy. This meant fewer units, along with settlement constraints and squad formations, resulting in less micro and more macro. Company of Heroes was the preeminent and most successful embodiment of this trend; but Kohan was among the most quietly influential titles that led to that point.

In Kohan, you command armies and cities instead of units and buildings. Think Total War meets Warcraft. Combine that with solid circa-2000 pseudo-3D isometric graphics, and iteration on the formula, and you get one of the hidden RTS gems of the early 2000's.

Better yet, I can confirm after just testing it that Kohan 2 works fine on 2560x - which is not something that every 20-year old game can claim.

So if you are into strategy games in general and RTS in particular, get this one when it's on sale. It's still playable, it's fun, and it deserves more recognition than it got back in the day.

Highly recommended to genre fans - cult classic.
