With the new Hitman game launching in a couple of weeks, I think it would be good to discuss tags for it ahead of time. This is complicated by the fact that they've decided to call it "Hitman 2", despite that being a game from 2002 - "Hitman 2: Silent Assassin".
The plain hitman tag is used for the 2016 game which was ostensibly just called "Hitman", although it was also marketed as "Hitman: The Complete First Season". As they decided against continuing the "series" nomenclature, it would probably be better to move these questions to hitman-2016. There's also one question tagged hitman-beta which is just odd.
