Legends, Nickelodeon GUTS, Double Dare 2000, Get the Picture, Figure It Out, and Nick Arcade are on "Nickelodeon Games and Sports" or "Nick GAS".
I used to look forward to getting up at 5:00am, when they used to air a one-hour block of my favorite kids' game show: Finders Keepers. Unfortunately, after 9/11/06, they took it off the schedule.
Another gripe I have with Nick GAS is that the shows are repeated six times a day. The only good thing was that if you missed an airing, while in school (or at work), it would come on again later.
As for GSN, I would rotate some of the shows that air from 7-11, so online players can have a variety of shows to play along with. Instead of a double run of Lingo, I would actually pair it with Chain Reaction permanently at the 7:00 hour. Both online games are very addicting to play.
