Srand has a Dev Diary posted, and recently posted some comments based on our (i.e. the fans) postings:
AC1 is all C++ for the game code, although we use a lot of Perl for simple data preprocessing tools. There’s some Java floating around for stand-alone tools, too, but that’s very new, and mostly Zyrca’s doing.
What else did she have to say? Go read the thread for yoruself!
