It'd be nice if we could zoom out or in (almost) as much as we want, like you'd do on Google Earth and games like Supreme Commander or Sins of a Solar Empire. We control so many units in C3 which cover such a large area that it's somewhat aggravating to never be able to view the whole battle at once, not to mention the frustration caused by the units that shoot further than a screen away. It's not much of an issue early on with small armies, but it'd make the experience considerably smoother with the large armies that are easy to attain.
Yeah, we all want that. The problem is, that Cossacks 3 seems to slow down a lot, when you do this. Try ENTER www ENTER freecamera ENTER. I think it's a hard task to get this done and it's probably not a priority for the devs.
