That a new Red Dead game could feature a significant online portion should come as no surprise. GTA 5's online world has proven so successful over the last three years that Rockstar put its entire development team on it.
Red Dead Redemption's online multiplayer included traditional deathmatch modes for up to 16 players, but GTA Online is a full-realised persistent world with millions of daily players supported with weekly and monthly free content.
