Unfortunately, the tournament thread isn't too much help for this. There is a listing of all the games along with the "Recommend Games" poll for each one, but it's really not very functional at all.
It requires several dozen clicks to look through the poll results for every game. Additionally, very few people seem to bother to vote (unlike the GSL games which get hundreds of votes, the MLG games seem to get 5 to 25 voters). And then the great majority of the games have a 90% "recommended" rating anyway, so the results aren't that meaningful.
Searching through 850+ pages of discussion for the most hyped games isn't an option either.
So if there were certain games that were really exciting or showed particularly skillful play, or certain entire matchups where the flow of the whole set of 3 games is a must-see, I'd really appreciate it if anyone could post about it in here. There were also a couple of people on IRC asking this question (what are the must-see games?) so I'm hoping a thread like this will be useful to some people.
