I think that's what made Euro 2004 so emotional for every single team that was involved; the atmosphere. There were so many different fans supporting their teams it was just a great atmosphere, and watching all the results boil over was just fantastic, and that's one thing I think lacked at the World Cup, other then that, the last World Cup completely sucked being played out in the night because of the weather that occured during the day so I expect a better World Cup in Germany in that sense; with hopefully games being played in the day. There's no better atmosphere for a game than in sunset hours.
Another thing that the World Cup has lacked last year (98 wasn't TOO bad;albeit not anything compared to its predecessor in 94), was exciting football. There just weren't that many memorable goals or anything like that, and the final itself wasn't too thrilling either.
