Either watching, playing or both it doesn't matter. l think i am going to be in the majority when i say for me it has to be Association football (soccer) because there is no other sport that comes close to it in terms of passion and ferocity, it really is in a league of it's own. Now there are probably over 50 sports out there so i will only include the main ones in the poll so you'll have choose other if you're into less popular sports like Athletics,cue sports or aquatic sports etc.
