TOKYO, Aug 3 (Reuters) - Japan’s Nikkei index fell on Tuesday along with other global stock markets as rising cases of COVID-19 weighed on sentiment, while video game makers dropped after Chinese media labelled online gaming as “spiritual opium.” The Nikkei share average slid 0.8%, dragged by a 8.71% plunge in online game producer Nexon. Konami Holdings dropped 3.39%, DeNA fell 2.64%, Bandai Namco Holdings sank 2.62% and Sony Group slipped 1.52%.

Chinese markets were also lower as the Delta coronavirus variant spread from the mainland’s coast to inland cities. Wall Street stocks too closed lower overnight as investors worried about the U.S. recovery after cases spiked.
