I agree with Jürgen... not only is everyone accustomed to it but it adds to the Game without detracting from it as some High Resolution games can.I think the image shown in the screenshot is really "good enough"
I have basically been under the impression that we all wanted more ability to Change and Add what we wanted in the Original Game without changing the Graphics, keeping the "Tools" and Thousands of Graphics and Unit Work that has already been created able to continue to be used.
I continue to believe it would be best to keep all we can as it is in the Original CIV game that has to do with being able to Use what has already been Created... also adding that if the existing Games (MODs) could be adjusted without too much time and effort like Starting Over, that would be Excellent.
If the above cannot be accomplished, any new and improved Game Engine that comes close would be used at least for New Games and if existing Games would require too much work to be able to play in the New Game Engine, they would simply stay as they are using the Original Game Engine. That will probable be the case but this is all still being evaluated for what can be accomplished. For example, Eric has said he plans to post about making a New Game Engine from scratch and has alluded to it being able to play existing MODs and using the "Tools" and what has already been Created. While this seems too good to be possible, I am certainly looking foreword to seeing his presentation.
