They don't BUY maps, and we've had shouwa forever, moreover, any versions that create maps freely share between others for the most part. Although they pay a bit, it's not much at all. ~_~;
Anyhow, chances are since it wil change the ESRB rating, they won't go around and add in Shouwa, if they did they would have to change the ESRB ratings first and THEN change all commercials and Ads to say 18+.
Losing more than half their fandb? No wai, gg though.
