AVC: If you were to embed a playable retro title into your game, what would it be and why?
BS: Well, there’s actually been a conversation about if it were at all possible—which it’s not, let me emphasize—but we wanted to put a Crash Bandicoot game inside. Not gonna happen, though. Don’t worry.
AVC: Certain people would’ve loved that, though.
BS: Yeah. It’s not our title. Sony doesn’t own it, so we don’t have control.
