State media reports that of the first 20 titles it assessed, nine were refused permission to go on sale.
解析：这里的of等于among，从句的主语可以看做是“nine of the first 20 titles it assessed”， it assessed是定语从句，修饰titles
It was announced in August that a new body - the State Administration of Press and Publications - had taken over responsibility for approving games and that it would limit the number of online titles available.
Nor was there any hint of when the freeze on new releases might end.
解析：倒装。因为前面一句话有否定。可以还原成“there was no hint of when the freeze on new releases might end”。When引导名词性从句。
