I've been using c-script less and less over the past couple of years. Moving more and more code into C++ .dll(s).

I can see using c-script as the data driven part of making a game, but I've almost totally abandoned this approach for external ascii and binary files that I read in with a custom tokenizer I've written. If you can't program C++, or are making a small game, then c-script is the answer, but conversely C++ is a powerful tool to make mid to large sized games.
