No it's not, maybe if your playing as New Zealand it is! I play on hard in rugby challenge 1 but in 2 I'm playing on medium cause the rucking is a little but more difficult, and the ai has improved. The game is really awesome though and they fixed up the annoying offload thing a little bit.
Depends on the person i suppose, but i have it and it is quite difficult at rucks to win the ball and it depends who you play against.good game though
