"We did reach a time in our first party, where the number of games and studios that we actually had […] put a lot of pressure on everything," said Spencer while speaking to Kotaku. "And it became more difficult to manage a portfolio when you kind of needed everything […] to hit the date that it had picked three years ahead of time [and deliver a] very high level of quality. The support that we’re getting now and we’ve had over the last couple of years has allowed us to invest in our first party, adding eight new studios and really create room for us to focus on quality."
So more studios mean better quality, according to Spencer. Having more studios is one way to get more games, but better games? I'll wait and see. But glad they admit that they dropped the ball this gen game quality wise and are doing something about it.
