A few suggestions (although it may be too late at this point). If you liked, but are bored of, Ghost, you should give Superghost a try. In Superghost, you can add letters to the beginning or the end of the under-construction word. (There are also a number of more complex variations, but Superghost is generally the best.)
However, the champion game of that sort, imho, is Botticelli, which works as follows:
One person is “it”. That person thinks of a famous (ie, EVERYONE playing knows who it is) character/person, real or fictitious, alive or dead. This doesn’t necessarily have to be a human being (Toto, Secretariat and Mickey Mouse are all perfectly legitimate), but it must be a single individual (not “The Beatles” or “The Hatfields” or “A Storm Trooper”). The person who is “it” then announces the first letter of that character’s last name (or, in ambiguous cases like “The Human Torch”, whatever letter the character would most likely be alphebatized under.)
All the other players then attemp to think of who it might be, given the information they have. When they come up with a hypothetical possibility, however, they don’t just come out and ask “Are you Bill Clinton?” or whatever. Instead, they ask a question about the character they’re thinking about. “It” has to then correctly identify who it is they’re asking about. If “it” fails to, then the asker gets a “free hit”, which is a yes/no question that “it” must answer truthfully. Thereafter, the field of possible characters to be asked about is restricted to those who fit all the free hits so far asked.
OK, that was confusing. Here’s a short sample game (with commentary):
It: OK, I’m thinking of an M.
Other: Do you have a friend who’s a flying squirrel?
I: No, I’m not Bullwinkle J. Moose
O: Are you someone who is worshipped by large portions of the world’s population?
I: No, I’m not the Virgin Mary
O: That’s not who I was thinking of… are you a male who is worshipped by large portions of the world’s population? (note: the answer given was a legitimate answer to the question… thus the asker had to provide more information, and “someone other than the Virgin Mary doesn’t count as more information”)
I: No, I’m not Mohammed
O: Are you a famous bully?
I: (thinks for a while) I give up
O: Nelson Muntz
I: OK, you get a free hit
O: Are you real?
I: yes
(from this point forward in the game, fictitious characters can not be asked about)
O: Were you in prison for many years?
I: No, I’m not Nelson Mandella
O: Did your most famous moment involve doing something “over the shoulder”?
I: No, I’m not Willie Mays
O: Was your nickname “The Man”?
I: I give up
O: Stan Musial
I: OK, another free hit
O: Are you alive?
I: No
O: Is there a common adjective that consists of your name with “ian” stuck on the end?
I: No, I’m not Machiavelli
O: Were you known as “Il Duce”?
I: Yes, I’m Benito Mussolini.
