Sounds good, except I thinking predicting every match result is just too much, so if it keeps up for the knockout stage (that second round and up, right?) that seems nice.
I said I don't think people should be allowed to vote for this you already set for the first round, because they would have an advantage, even if worth less points.
So if this is it until the first match, then then the first round is over you start a new round that accounts for the knockout round with match results also point worth, that seems nice, but would you add a new predictio round for each stage? (Quarters, semi, finals)
I'm not sure what you mean in your 2nd sentence. @bold that's covered by individual match predictions. So you'd predict top 2 teams for the group stage (as well as your pre-tournament pick for winner/golden boot). Then after the group stage ends the quarter/semi/finalist/winners all at once before the knockout stage starts. But you're also predicting the individual matches as it goes along, which gives you something to predict during the group stage, and you can also pick up points for the knockout stage matches even if your original picks to progress didn't make it.
Plus with the individual matches you don't have to predict them all in advance (you can if you're a masochist though ). You could just post who you think will win and what the score will be on a day by day basis.
