If you're gonna do a Price is Right video game, it has to be in the next generation of video games (PS3, Xbox 360, Wii), so you can store more information and stuff.
Research the game and how every game works, and the situations within. Don't do dumb decisions like the 1990 computer game did.
Try to do games that can be playable in a video game. For instance, It would be hard to do games with a clock like Clock Game or Bonkers. Get buttloads of prize announcements, even if you have to stick Rich in a recording studio describing hours of prizes.
If you're gonna have unlockables, have reasonable ones, such as behind-the-scenes stuff about the show and game, don't "unlock" certain pricing games until you get $x, it's gonna get annoying quick having to play the same 6-12 games. This was one problem with BigJon's game.
If you can't get Bob, get somebody else, and make sure he's on the stage, and not a disembodied voice like the DVD game.
And of course, lots of statistics for players, games, etc.
I personally can't think of anything else, although I bet a couple of you have ideas...
