Hmmmm, let me think for a moment. 1) Perhaps they could assign themselves some kind of mission for a season from which stories could be derived. Mission: Earth, Mission: Repaint the ship, Mission: Complete all the crossword puzzles. 2) RD is big. They should go exploring. This means new sets = $ 3) They can meet nice GELFS, who end up getting destroyed by bad GELFS (following RD) just when things are looking up. New gelfs, not the ones we've already seen. 4) Giant mutant plant escapes from the greenhouse area of the ship and wreaks havoc. 5) New game gets out of hand (full contact tiddley winks, Laser Tag with real lasers, Headstone Dominos, etc...) 6) Cat tries to learn engineering 7) Visit more worlds 8 ) Work less with Time travel, more with the teleporter. (makes 7 easier) 9) Run across an unmanned deathfleet heading towards Earth, but they can't figure out why. 10) They run out of coffee. I prefer new ideas to rehashed old ones. a little cameo here and there is fine, but too much is TOO MUCH! If I feel like seeing Dwayne Dibbley, or Mr. Flibble I just pop in a DVD.
