Let's not count out a LOTHT yet.
Arguably, the 3 biggest franchises for game shows is Guts, Double Dare, and Legends.
Double Dare kept getting revived, the most recent being Double Dare 2000, and Guts has been revived (but is now on hiatus).
With the creation of BrainSurge, this maybe a new leaf, and game shows maybe coming back.
I'm on DirecTv, and this is Channel 299 lineup staring at 12:00 (obviously in 30 minute intervals)
Victorious (1 hour)

iCarly

Then goes Nick at Nite.
If Nick would revive Legends, and pair it with BrainSurge for an hour block of game shows, or would just re-air the show and replace it with one of the Victorious or Big Time Rush slots above, I think Nickelodeon would have a lot of success with it.
