Is it possible for openBVE to host simplified Chinese, because a lot of people from China cannot understand traditional Chinese. Also, could somebody make some Chinese routes, just for the sake of our Chinese people? By the way, I'm more than happy to translate anything into simplified Chinese, from English of course.

Feel free to make a translation. The file to translate is language_en.cfg inside the Interface folder. Please take a look at http://openbve.freeforums.org/translation-of-the-simulation-t237.html for more information about translations.

Moved to Translations and internationalization.
