When The Line was in development under the 2014-15 GSN upfronts, the show was suppose to be a regular series and travel to multiple cities. When The Line was green-lit in July, the July press release noted that The Line was green-lit for five episodes.
Filming for The Line did not go as well as GSN would have wished, hence the two-hour special that aired on December 23rd (versus five one-hour long episodes).
Come September out of nowhere, GSN published a casting call for Baggage: On The Road and then green-lit the reboot for 20 half-hour episodes. All of a sudden GSN had turned Baggage, a studio-based game show into a traveling game show. A reason for that? Possibly because GSN did not want to shoot more of The Line after Nashville was (what appears) remotely unsuccessful.
Baggage: On The Road filmed in four locations: Connecticut, Tampa (FL), Austin (TX) and Louisiana. Were those possibly the four cities where The Line was suppose to film its remaining four episodes?
I will agree that Baggage deserved to be brought back but I never saw the reason for the "On The Road" format. GSN had no problems recruiting and casting contestants for the original version, which filmed all 300 episodes in Los Angeles. It may also be true that GSN had previously considered bringing Baggage back
I heard a bubble in the Summer of 2013 that GSN had considered bringing Baggage back for new episodes. By rumor, GSN passed the Baggage revival to produce Mind of a Man instead.
This is me simply theorizing Game Show Network but it was a real possibility, and a quick-fix solution that GSN did not like The Line, had cities left over and had little options. With the few options, Baggage was apparently one of them. The timetable does make sense.
But hey, it seems really odd that Baggage is now a traveling game show.
