I know this is a "old" thread; however, I like the idea of GURPS, but never really can get into it when compared to CT.
However, since I like using GURPS for the hex grid combat, I found a copy of The Fantasy Trip Traveller, and that is GREAT.
I just played a quick battle with my niece and nephew - rules light enough for little ones to learn, but gives them something to think about when they play like a boardgame. It kept their interest very well.
However, ::laugh:: who can resist a plea for help from Gramma Nutt to rescue Princess Lolly from Lord Licorice, while Mr. Mint is the weapons/arms dealer and the battle takes place at the Gumdrop Pass. (yes those are Candy Land references so you know my age group of players) ROFL
