As far as I was concerned, both versions of Carmen Sandiego would have been counted together. Although nobody tried to vote for Where in Time separately.
Since I was using Matt's rulings as to what was and wasn't the same show, most of the tough calls had already been made for me. The only difficult decision was whether I should include Catch 21 along with Gambit. Ultimately, I decided to group them together, citing the precedent that The Who, What or Where Game and The Challengers had been grouped together in 2006.
That specific ruling only came into play once -- in that instance, the voter had placed both Gambit and Catch 21 on their ballot. They removed Catch 21, which had been ranked lower, so technically, my decision did not have an impact on Gambit's final ranking.
I'm still examining the final tally, but I will say, I'm seeing a couple of interesting results in the top 50. I'm looking forward to seeing the group's reactions.
I'll give you one spoiler: Once again, nobody in the game show fandom voted for Studs.
