I think this game is so entertaining and exciting (as it has kept me interested for ages) and it deserves an 8 rather than a 6.5!
The licensing issues can be worked around with a patch, the game can be refined by adjusting the gameplay sliders and on the harder levels, the AI are much smarter just like a real rugby match.
It is THE BEST RUGBY GAME without a doubt on the PS3. RWC 2011 was just a regurgitated Rugby 08 game with only international teams and fancy styles (on that topic EA have not made a rugby game since Rugby 08).
Can't wait for Rugby Challenge 2!!
