Occasionally there comes along someone with a question in french or german. Usually a bilingual Mod or some of the community will help them out. So you still can get help here if you don't speak english
True. There are people from lots of countries here, as it is really easy to buy the download version of game.
I am german and i had to order the US Version, because there is no german version of Dark Avatar/the Gold edition (at least in stores).
