I like it, but do you get just three words, or is truly like Go and you have a stack and can pass if you desire?
Honestly I didn't think about it that hard, but since passing through words "to get to the easy ones" would be a really bad time-wasting strategy, I'd be cool with a stack of ten or so words.
It would fit except for the fact it flips the game on its head and you've suddenly got a team playing a category with an upward-counting clock. That would stick out more sorely than the way they slapped the logo on the front of Michael's lectern.
The tiebreaker as it is now sticks out with the weird explanation and the dramatic reveal. If the count-up bothers you that much, start a clock at 30 for the first team. and let that be the maximum time, a la the 99 second time on Scrabble. If they somehow crash and burn and can't score 3 farking points with Words That Begin With This Letter, the other team simply has to tie in less than the 30 seconds. I'm not going to worry about the one-in-a-million "they also got 2 in exactly 30 seconds" situation.
