I've recently downloaded Tom Clancey's Spilnter cell: Conviction from Steam, and have been playing and loving it for a while now. The game plays out similar to a Tom Clancey novel; Korea starts showing aggression to Japan, and you, special agent Sam Fisher, are sent in to fix things before things get hostile. This is the first Splinter cell game to be rated M for Mature, most likely because you are given a knife, which gives you the option to execute enemies using it. No blood is shown during these scenes, though small amounts can be seen when shooting an enemy. There is minimal swearing, the worst I've heard being "sh-t", but nothing stronger. The game rewards you for being stealthy and not killing people, executions leading to a lower score at the end of the mission. The game has an average difficulty, sometimes involving trial and error, but generaly stays challenging but not frustrating. I would rate it +13 years and older, though more Mature 11-12 year olds could easily handle the content.
