Believe it or not, there are a lot of people that don't want games only in English in Europe.
Subs are ok, but some want audio as well.
As for me, theres like maybe 5 games translated in Slovenian (as subs) and my English is good enough so I'm fine with English only. Actualy no, I wouldn't want to play a game in Slovenian anyway, so hell yes for English.
