All good options. Besides they, I wouldn't mind seeing revivals of:
-Bumper Stumpers; main game basically the same as it was for most of the run, with the addition that if a third super stumper is needed, it'll be sudden death, with each symbol in the plate except for the last one revealed one at a time until someone buzzes in with the correct answer; if neither do, another tiebreaking super stumper is played until someone does win. Bonus round would be in 2 parts; as with 1986 Card Sharks, the first would be for cash--solve 7 plates in 45 or 60 seconds and win $10,000 or more--and the second would be for a car--an updated Final Stumper with a graduated set of odds (i.e., a first time player would find a board with 6 stop signs and one Win or Car screen behind the S.T. U, M, P, E, and R; if they pick the right screen, they win the car and retire; otherwise, if they make it a second time, one stop sign gets replaced with another Win/Car screen, and so on until they win it automatically if they win 7 games)
-Caesar's Challenge; the concept could work divorced from Caesars Palace, perhaps on a set that looks like a Roman forum or colisseum. Main game would be more or less the same; use the first bonus round, with, as the previous example, if they make it 9 straight wins, thus earning all 9 letters in the final word, they win the car automatically
-Trump Card; same logic as above, since it would not have to be at a Trump property. Tighten the main game; first round is to be the first to make a line across the center of their card. First contestant to make it across and whoever's further along among the other two contestants after time's called move on to round two, which is a race to cover as much of the card as possible. Player furthest along at the end of the round moves onto the final round, which would be more or less the same
-Wipeout; no real need to change anything in this case
-The Big Showdown; I've only seen the episode where Jim Peck falls coming down the stairs, but the concept looks like it could be a winner mostly as it was
-Whew(!); throw in a facet along the lines of a "block breaker," for the charger to use (but only once per charge) to even out the main game's odds a little bit, and otherwise it would be great as it was
-Crosswits; base it off Jack Clark's version's rules, but keep David Sparks' graphics
