Today we launch a title, and often – if not always – put out DLC. We’ve talked about recurrent consumer spending, where we have offerings where fans can engage and spend money on an on-going basis.
“With GTA V, we have sold 32.5m units in to date, which is extraordinary. 70 per cent of people that have played GTA V while online have played GTA Online, which is a free-to-play experience. And recurrent consumer spending related to GTA Online represented nearly half of our digitally delivered revenue in the quarter. So people are voting that they want to stay engaged and they are voting with their wallets.”
