I'm new to BGG (so be gentle) and wanted to start rating the games that I own/play. However, to be fair I wanted to come up with a personal rating system and once I did that I, I thought it might be worthwhile to put the results in a review. I hope it is helpful for those in a similar situation. Constructive Criticism welcome.

Who I am/ Who Might Find This Useful
While I do occasionally play games at a local gaming group, when I buy games, the intent is (1) playing alone, (2) playing with my kids (ages 3, 7, and 7) or (3) playing with my non-gamer wife and friends. So the most important things for me are: (1) theme (to interest my wife, it can't just be pasted on), (2) degree of luck (not too much but more than just trace), (3) screw you factor (my wife likes these games – especially if there is an ability to gang up on the king), (4) adaptability for kids, (5) adaptability for solo play, (6) appropriate for large groups and (7) playing time.

Number of times I've played: 20+

Overview
A clue-like game where one player is Mr. Jack and the other are the detectives trying to capture him/her. Mr. Jack is one of the 8 detectives in disguise attempting to either leave the city or stay hidden for 8 turns. The detective player tries to separate the detectives into those seen/unseen to iteratively pare down the number of possible suspects. When(relatively) sure, he/she has a true detective find and capture Mr. Jack.

Theme (1 = trace, 10 = transports you to a new world)
The game has little theme to place it in the late 19th century London and could as easily be looking for Son of Sam as Jack the Ripper. That said, there is a strong detective theme with a feelings of deduction and deception. Score: 4

Degree of Luck (0 = trace (go play Chess), 10 = all luck (go play War))
There is a little bit of luck based on which characters you get to play on a given turn and as a result of using Sherlock Holmes' special power. However, almost all information is visible so this is mostly a game of logic and deduction. Score: 2

Screw You Factor (0 = multi-player solitaire, 10 = Winning is 2nd priority)
While the detective player depends mostly on deduction, as Mr. Jack, knowing your opponent and manipulating them into believing what you want is almost a requirement to win. Although this isn't screw-you, it is far from multi-player solitaire. Score: 6

Adaptability for young kids (ages 3, 7, and 7) (0 = unsuitable, 10 = built for them)
So far I haven't tried this game with my big-kids. There is very little reading required so that wouldn't be a problem. However, I think the deduction part is still beyond them, at least without help. This may be something I try out in the next year. Score: 0

Adaptability for solo play (0 = unsuitable, 10 = built for it)
Unsuitable. Score: 0

Appropriate for large groups (0 = unsuitable, 10 = built for them)
For those wanting this sort of mechanic, I would suggest either Scotland or Garibaldi (though I haven't played this yet). Score: 0

Playing Time: Average: 30 minutes

Summary:
I don't know why this gets as much play time with my wife as it does. My wife enjoys this game and has even one once or twice as Mr. Jack. Although I win more often as Mr. Jack than she does, I still lose 2 out of 3. I think the attraction of the game is that we can get 2 games in in an hour each playing Mr. Jack once and games are usually close. Also, this game doesn't take up too much space, allowing it to go to a restaurant and be played with restaurant lighting. Personal Score: 6
