9. Death Stranding / Cyberpunk 2077
Two of the biggest games in recent years both in size and mindshare, players have combed through both these worlds tirelessly. And of course, with a Hideo Kojima game, there's always going to be more references and Easter Eggs to find, but in this case, the connection between these games resides with Cyberpunk 2077.
... When the game is actually running at a steady framerate, that is.
After getting to know River Ward, V joins him in a mission called 'The Hunt', which has them breaking into a building looking for files on Anthony Harris. Though once inside, there is something way more interesting than just a couple of files.
In one of the rooms, a Death Stranding "Bridge Baby" can be found. Now, somehow this infant has been separated from Sam Porter Bridges, so maybe it is his one day off or it was stolen.
BB can't be interacted with, but can be scanned for a little more information. Either way, it would be cool to see Hideo get his hands on the Cyberpunk universe one day. Make it happen, CD Projekt Red.
