I pretty much dislike, to varrying degrees, all game shows, because of the banal comments of the hosts, the wasted time, etc....but I do like trivia, I like knowledge-based games, and so I do like to watch some and play along. Jeopardy is probably my favorite. I never liked Who Wants to Be A Millionaire much because too few questions are asked, and they are too culturally oriented.
Jeopardy is the most straight forward of the question based game shows, has the least gimmicks, and packs in the most questions on a single show. I don't think I'd watch a complete show of anything else.
