In making an RPG or Graphic Adventure like game, what would be the best approachto create a 'dialogue engine' (bunch of logical RPG-like dialogues or conversations). A binary tree, a graph, or embedding some other language in the C/C++ code, like a scripting language or something like Prolog???Or actually creating some engine myself?kvarnerexpress
