Metal Gear Solid 5: The Phantom Pain takes the stealth/action of the previous game in the series and puts the player in a nonlinear environment to use these tools. Like The Witcher 3 the player can then chooses how to complete the story in a very nonlinear fashion. Despite existing in different universes there are similarities too between Geralt and Big Boss. Both stoic warriors with great amounts of experience that exist in the grey area between good and evil who have overcome many challenges. The Metal Gear Solid series is a warning against the military industrial complex and The Witcher Series has also always set out to tell a good story.
