I believe one of the most important reason for those players have illegally dl Bs is ED didnt release the product properly. Like the western and Russian versions dont get released at the same time, and the Russian version can not be purchased outside CIS.
I can see a lot of ppl around me have already played BS illegally these days. I believe the fact of this is from ED itself by some reason.
However, I will definitely wait for Demo and get a western product in next yr, although i can see so many ppl have already started enjoying BS(they are Russian Players and those dl the product illegally)
