This is an early RTS that got a lot of things right, well before other games in the genre. In particular, the way troops are organized into squads that gradually replenish themselves while in home territory really takes a lot of clicking out of the equation. The clickfest thing has always pushed me away from RTSes, so it's no wonder I found this appealing.
I owned a retail copy of this game more than 10 years ago, and when I found it on Steam I wound up getting it so I could finally finish playing through the campaign. I tend to hop from game to game a lot and not finish things, but this was one I wanted to play to the end. I finally beat it (it's not particularly difficult on Normal, except for the last level; I haven't tried Hard yet), and am looking forward to trying the other two Kohan titles that exist.
From a modern eye, there are one or two things to put up with when playing this dated title. The low resolution is a given, as is the resulting small viewable area. When you order your troops around, or even click to select them, their vocal acknowledgements are annoying and repetitive. Various other small bits of interface clunkiness, but overall I think you'll be surprised how many things they did get right.
The Kohan series never made it big, and it's certainly not a well-known IP. Kind of a shame; perhaps someday someone will acquire the rights and take another stab at it. Then again, the story is not really the selling point for me.
