A few years ago I did my own editing of STA2 where I improved AI tech Trees and aggressiveness and as well the enlarging the visual playing area with larger maps, now when I am trying a single player mission the visual area is so small, structures look way to big on Fleet Ops and STA2, does any one know the edit locations, for the life of me I cant remember and I cant find my old files I modded
At the top of the RTS-CFG file there is "overview-max-height". You'll need to change that value. FO uses 1850 and stock was 2200 so have a play with that.
