Like Rugby 2005 where before you began you had to pick a country. Let's say when you start this mode you must pick a country and depending on what country you choose, decides which teams you will be eligible for. Since I'm a New Zealander, I'll pick New Zealand. Then my season starts off in the Super 15. So I get the option to select one of the five New Zealand franchises you play as. I'll pick the Hurricanes and commence playing the Super 15 tournament. During the tournament certain players would have performed better than others, injuries would put players out of commission and by the end of the year all the New Zealand franchises would be hoping for All Black selection. So the form players of the tournament will be selected for the All Blacks[Like in the NBA titles, how certain players are picked for the All Stars depending on their performance throughout the season]. Then we'll start off the beginning of the season tests against the Northern Hemisphere squads[random or simulation]. After these matches will birth the beginning of the Tri-Nations. Then the end of year Grand Slam tour. This continues for four years until the World Cup and in between have the British and Irish Lions tour[not sure how frequent this is]. During the entire Season Mode have a news hud quite like the World League news feed but have these feeding news from all the other international squads playing each other in their own test matches. And judging by each teams succes/failure the IRB world rankings could be implemented as well.
