1. The current composition of graphics unit is final or planned changes (change of graphics of some units or addition of specific varieties for different countries)?
At present there are no changes and additions of units planned. Please don´t forget, there were many hundreds of units and some complete new unit lines added to that mod. Until now I have no feedback about these added unit lines (for example the Mach 2 aircraft, amongst them the Mig 21 and the Phantoms and Starfighters. So I don´t know if these added units make sense for the gameplay in other eyes than mine.
2. I understand that now you are doing the project CCM 2.0, and come back to work on RARR only after its release?
If errors are reported for RARR, I try to fix them. RARR is not abandoned while working on CCM version 2.00.
3. If it is possible to estimate, please willingness RARR (percentage or the necessary time) to the output of the release or stable version.
In my eyes there will at least be one more version of the RARR mainfile. At present this is a betatest for RARR as I didn´t have the time to test all entries myself, if they are working properly.
A stable version
: A version is stabel, when it is working completely well for the individual player. So when no more errors are reported for a longer times about the graphics, may be that version could be considered stabel in the matter of graphics. I cannot say when the current graphics are "stabel", as at present there still come reports about errors - that must be fixed.
A stable version about sounds for all players at present still is not possible, as Firaxis set different levels of sounds in their different versions of Civ 3. Please remember the post of ynot56 asking what is an amb-file. Later versions of Civ 3 and C3C did receive amb-files for sound by Firaxis, older versions didn´t. May be here you have to wait for CCM version 2.00 as here I try to fix that problem caused by Firaxis by a new modded C3C mainfile.
And there are problems simply triggered by other persons outside the RARR mod that can make the mod "unstable", for example the unbelievable new ###-Steam-upgrade for CivComplete, that killed the labels text of all existing mods and scenarios (here a patch is inside the RARR-textfolder) or the "wonderful world" of the new Windows 10.
