Me too! But, during the development of Hegemony, my opinion has changed...at least for now.
I started our wanting to represent armies as close to a 1:1 ratio as was possible, but we final settled on approximately a 50:1 ratio for infantry/cavalry for various reasons: the flexibility to zoom in close for detail shots and making the units oversize (50 meters tall) for ease of viewing, were the main ones.
These two old screen shots show a formation of hoplites winding their way through a mountain pass. As you can see, they are hard to see, even at a 50:1 ratio and 50meters tall. In the more distant view, it's especially hard to see what's going on. The other effect of vertical distance is that the height of landforms is hard to make out. (The mountain tops have snow on top.) And if I hadn't altered the terrain to allow the passage of the caricatured (oversize) troops, then mountain passes would be sliver-thin and all but invisible.
Now, in defense of the 1:1 idea, these shots represent an extreme that we experimented with and are the main reason that, when zoomed out, we transition to a "parchment style" 2D view with plastic look miniatures. A 1:1 ratio is probably doable in a battlefield/battleboard game with less distant views, but, we were after the continuous ebb and flow of strategy, where you spend more time maneuvering and mopping up after, than in actual battle....and all in the same scale and on the same massive, continuous map.
It's always a trade off and I think that we've maintained a semblance of that feeling that you and I are both after as exemplified in the other two "old" screen shots that show battle field maneuvers and phalangites camping.
The trick is to create the thrill of immersion, while maintaining an ease of identification and flexible control over units. Our goal is to make a good, playable game that accurately reflects history. The audience will soon be able to tell us if we've succeeded or not as Hegemony will have enough of a demo mode to make it a solid try-before-you-buy wargame. Release date: early in the New Year.
