Question: So... I just got Hitman: Absolution for PS3. I have started playing a few missions, but I feel like I am missing something.

Do I feel like I am missing something because I haven't played the other Hitman games OR of my failure to understand the story due to some other reason?

**Should I play the other Hitman games to understand the story?**

Answer: 
well its good to start with hitman codename 47 to get to know the story better or watch videos on the games
Not really, but i do recommend you do play the other ones :)
