It's fast, fun and people can play it together and go crazy. The teams have different strengths and weaknesses, so watch out.
I would rccomend New York because they are well-balanced. Chicago is great on D but comes up weak on offense while Miami is exactly the oppoisite.
As for strategy, I might do a guide or FAQ if enough intrest warrants. But here's a quick thing. Take NY. On defense, take Lawrence Taylor. You'll have to search a bit to get him. Follow the bottom 2 recievers.
When one gets highlighted with a "2", follow them. Get so you are running right with them. You'll see an "X". Get on that X while he is and you'll intercept the pass.
THE FUNFACTOR IS SO GREAT, DON'T WORRY ABOUT THE REST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
