Well it's apparently dumbed down
Quote:
Rugby union has more laws than rugby league[23][24] and it has been described as being more a complex game.[25][26] Rugby league in turn has been described as a simpler game that is easier for spectators to understand.[27] Mat Rogers, an Australian dual-code rugby international player, has said "Rugby [union] is very complicated and rugby league is much more simple in comparison". England's Chris Ashton, also a dual international, has said that union has "more of a tactical side, more that can happen in a game". Ireland's Tom Court, has said "Rugby Union is a complex game with certain closed skills like scrummaging and line-out lifting and rugby league requires a higher level of fitness to compete at the highest level".[28]
I was surprised when I started getting into it a while back that League was the more popular when I read up on it.
I dunno if it's just because I was exposed to Union first but it def appeals to me more. League just seems truncated.
