Speaking as someone who has done fifteen shows on my campus in a two-year span, perhaps I can be of some help...
I have not received any legal flak for doing college versions of television game shows (currently running or otherwise). I always title my shows based on what I am doing (eg. Family Feud, Password Plus, The $250 Pyramid), advertised it on flyers and our college newspaper, and have had no problem.
As long as the issue stays internal (that is, as long as the event stays on campus and is not spread to outsiders or not taped for the intention to be aired on television), you should be okay. Everything that I do concerning the shows are screened by higher-ups, and I have had no problem so far.
There is nothing wrong with playing it safe, but I do not think that Sony would be paranoid if you did a campus version of "Pyramid" and called it such.
