“They’re making a broader point that devs should be allowed to experiment and fail in new genres rather than be confined to what they’re known for. Otherwise we’d never have gotten games like Horizon, Left 4 Dead, PT, Uncharted, etc.”

Hopefully the days of just Halo, Forza and Gears as the only mainstream Xbox IPs will be over rather sooner than later.
