Regarding changing the font, has anyone ever tried renaming the font you want to use LSANS
Yes... IIRC the way to do that is described best by taube in
this post. I also found a different way to accomplish the same basic goal on Windows boxes, which I described in
this post. In both cases, it allows you to use a different font, though not quite as straightforwardly as renaming the file.
While that doesn't allow you to directly increase the size of the font, if you have a font that is larger in the same nominal size, it can effectively allow you to somewhat increase the font size. Occasionally this causes the font to overflow the area where it's supposed to live, as seen in a couple of the screenshots I included in the linked post, but it may be worth the tradeoff, particularly if like
@keldath you're seeking a larger font.
Vuldacon mentioned the other key way to achieve the basics of the goal, via resolution. By default the game should tell the monitor to use 1024x768 resolution, but if you have the line KeepRes=1 in the conquests.ini file, it will not do that. If that is the case, removing that line will make everything effectively bigger, at least as long as your monitor scales the 1024x768 to the full size of the screen, as opposed to putting black borders around the game.
