Want to play Fallout 76 -- the first online multiplayer Fallout game -- with friends across PS4, Xbox and PC? Too bad: Bethesda's Todd Howard told GameStar.de that though he'd like to do it, Sony won't let it happen.

"You cannot do cross-play in 76," he told the publication in a video interview. "We'd really love that but right now we can't."
