We don't, I think. As RPG gamers we need just games. The market is necessary for publishers and authors to make money. A side effect of the market are games. Do they really need to be created in Polish? Do we have to be slaves of translations?
Back in time there were people socially excluded - those who couldn't read and write. About decade ago people without internet connection were considered as excluded too. Today people who couldn't read English on basic level are in my opinion excluded from the culture. Modern illiterates. Limitation to own language hurts and reduce possibilities a lot. Think about all those books, films, tv shows, games which you could never taste because of a language barrier.
