Waay OT, but as this place is the virtual equivilant of a small closet in a dusty wing of the site, I don't really care.
No link i'm afraid, I did all this back in '02 and never shared it or stored it or anything

mad

If there is a mod that does this - I don't know where it is. But it's not very difficult to do.
-Units. Draw some new units, or DL a load off of here or Apoliton if you are a lazy sod like me. Most are better than the standard stuff on the vanilla. Simply C+P them over the file (remember, open it as a .bmp)
-Cities. Out there, somewhere there are several city sets which follow the isometric square rather than the **** ones that are there at the moment. Try looking in scenarios. Again, just C+P them over.
-Terrain. A little harder, as to get all the roads etc to fit together. Look in scen's that have full new terrain sets - I used one I 'borrowed' from a Europe WWI scen I found here back in '02.
-Improvements, wonders etc. They are all the same basics. Find something new you want, then look through the .bmps that are in your ...Civilization II\ file, then C+P over the original.
Or you could just wait for me to finish the one I'm doing at the moment. Should be finished in a week or so.
...I once managed to cram a working CII onto three 3½ floppies a few years ago. It was around 4MB, although I did .zip it up good and proper, after stripping it to the bone. Who needs torrent?
