Earlier quoted context omitted.
CMANO is great if you can get past the spartan graphics and UI (and to be honest the target market for such games probably doesn't care much about the presentation as long as the gameplay is solid). There's something uniquely satisfying about watching military engagements play out as you direct the units.
Don't forget the rather high price for a "video game". I do find it interesting that the group behind it distributes the database of unit information that backs the actual game for "free" (it's just available, with AFAIU, no hoops to jump through)

#31$80 is pretty nuts and I don't think I would buy it for that much. I got in on sale for I think $25.
