Bombur I doubt your idea will ever be implemented, good though it is.
-Me too.....but it seemed so easy in Civ3 editor....of course, I know nothing about programming
What would be possible though is to create a "wrapper" program (or even a batch file) which would achieve some of the same thing. This program could set up the "environment" for each mod prior to invoking the WitP EXE file. The user would not need to do any manual file manipulation.
AB's install utility does something like this but it does not include the WitP EXE invocation bit. It also requires the user to change folder and specifically run it, whereas with a wrapper program you could change the "War in the Pacific" shortcut to run the wrapper instead of the generic binary.
-A different executable for each mod? How it would deal with graphics, since different graphics for different mods share the same names. I still have the Bioeditor for ACOW, an exe file that loads speciffically databases for certain mods, however, it´s already possible to create new equipment databases for WiTP, actually it´s possible to create virtually any mod, as far the player is willing to accept that a G8N looks like a G4M[:D], so the big question is how to have the separate graphics, a trouble that is more similar to that one presented for Civ3 modders
