Did you ever play a video game that made you cry?
The Last of Us. It didn't exactly make me cry but I got misty eyed. Aside from violence, nudity, profane language and drug use, I never really put much thought behind game ratings until The Last of Us. The game was so intense and you become so invested emotionally in it's cast, I was left feeling like it was the only "Mature" game I'd ever played.
Seriously, highly recommended.
