It's a C+ at best for me...
I agree with those who say they shouldn't be given the last letter of the words. That is just not right to do in a game like this.
The betting round makes no sense, as it forces a team that's behind to bet big early, and if they don't get the first word or two right off, they're done (I think I would have at least been OK with it if the final chain was just higher money for each word, like $400-$500-$600-$800-$1000...at least it makes the last few words important even if a team is way behind)..
The Speedchain makes a little sense, but you could done something like a betting round there to improve it (say, give the top and bottom word,then offer them the choice of going for $300 if they can get it with no extra letters, $200 for the first letter of one of the words (their choice), or $100 for the first letter of both words- and for the last one, double the money)
Now I always liked the bonus round format, but for just double or triple the money? They couldn't have made it $100 a correct answer, $15,000 for 10?
On the positive side, I do like the graphics, especially the "railroad station message" letters....and the host doesn't want to make me throw something at the TV....
Let's just hope some of the problems were just early taping bugs, and they ironed them out...I don't know though...
