Wow, now this is exactly what I was looking for! Specifically, The Da Vinci and Nostradamus games look exactly like games I would play. All the other ones look really good too. Thanks so much!

Yea I should have mentioned in the original post that I am not really a big fan of shooters. I'm more into adventure games, point-and-click games, sandbox games, and such.

I love Mafia and Mafia 2, I also REALLY enjoyed all of the Assassin's Creed games. I've just been looking for a game that I haven't ever played before. Thanks for the suggestions so far!

I love games that are set in the past but I don't like strategy games AT ALL. Some games that I enjoy include:

Sherlock Holmes vs. Jack the Ripper

And Then There Were None

Titanic: Adventure Out of Time

Dracula - Origin

There's many more that I have but those just came off the top of my head. Any help would be appreciated.
