Game suggestion:Bioshock (1,2 and Infinite)

I know the games are an 18, but I think Ash and Sam would really like playing this game. The environmental storytelling in this game is fenomenal and the lore is something that you have to try and piece together and i really think they would enjoy it as it goes to some dark places and is really intriguing. The characters are really complex, and there is a MASSIVE twist. These games hold up after all these years.
