How many times can you compare the two versions of Scrabble or talk about the board game?
To answer the question, the '84 version, post-spelling. I liked both formats with the win 5 games, get $20,000 (10 for $40K) as well as the Bonus Sprint.
In retrospect, the 1993 version was good because it meant that game shows were on the air (I really did enjoy it as a child). 20 years later, it seemed pretty cheap, although I did like the deco-ish contestant island.
