Rugby 06 depicts the game of rugby fairly competently. It's fast paced, the tackles are great, side steps, charges, free running rugby are all well done. However the game just doesn't have the depth to make it a truly great sports game. For one lets look at the immersion factor: the commentary gets stale after about 4 minutes since it's the same thing every match and the commentary doesn't match the on screen action at times. The drop kicks are next to impossible unless you are standing in front of the posts or you are a computer. Also there are bits of the real game that are completely left out: where's the ref?
Bottom line: Overall the game is decent but it falls down in immersion
