Hi Kyriakos,
I have something "new" for you - and a great challenge, too as these are files that are forgotten by most Civ 3 modders.
I frequently play CCM as the standard C3C game, as this allows me to have the comfort of some additional options. One of these options is the use of the City view graphics. These graphics can only be seen in the standard game, but since C3C they are not accessable in mods or scenarios any longer. I could replace a lot of the existing city view graphics with graphics of buildings used in CCM, among them the Hagia Sophia. But a lot of other buldings in those graphics could need a refreshment by better looking graphics, too.
These graphics are mostly much bigger than graphics that can be used in C3C buildings-, cities- and resource-graphics. This means much more details of your artwork could be visible in these graphics.
Are you interested?
