I found out how to hack what people say in MNOLG. It's quite fun. Here's a sample;

The way you do it with the offline version is go into the folder called "MataNui" and scroll down until you find files with certain names(the one in my screenshot is called "surfer")and open it in Text or Textedit or whatever and delete the current words and put your own in, with + as a space. Some files are more complex, and have multipule things to change.(The first time you see Maku she has multipule answers you can say)Just read it carefully and you should find what you want to change.

Or you could skip all that and ask me to do it for you. I have a Mac, those intructions might be different for PCs.
