film noir target audience

I want to create a game cover for my film noir, so my audience would need to be interested in games or it wont appeal to them. Their jobs or any other hobbies wont really matter as long as they are interested in games. The age would probably teenagers and young adults because they are mostly interested in games, it might appeal to someone older since the theme is film noir and it might interest them to see what it is like, maybe it is something they remember growing up and can relate to it. Their socio-economic would not really matter as long as they are having some kind of money since they would need to buy the game
