It depends on what you like in a sport, if you like skill, intellegence and athletic ability you cant go past soccer. I personally prefer faster versions if playing, street soccer is/was awesome(dunno what happened to that).
In the other codes the main appeal to me is the random violence and "they" are trying to cut that out as much as those politically correct losers can. If you like violence in sport go for UFC etc. Still if you are into the ultimate in violence nothing beats real fighting, Rambo is far more enteratining than any violence sport IMO. Mugby is the best of the brainless codes, havnt played for about 8 years though :lol:
Im not really very fussy about sport, anything that can be watched while drinking a beer is cool with me.
