After last year's expanded Nation League set, it was requested to add further countries this year. All nations who played against 'Tier 1' nations are included, so all matches are playable, as well as other nations who played multiple matches against high quality opponents. There are therefore now 22 countries included in this set (which replaced the previous Nation League title) this year.
 
Countries included are: [Tier 1] Argentina, Australia, England, France, Ireland, Italy, New Zealand, Scotland, South Africa, Wales; [Tier 2] Canada, Chile, Fiji, Georgia, Japan, Portugal, Romania, Samoa, Spain, Tonga, United States, Uruguay. 
 
Fiji (home) and Chile (home and away) have had estimated team ratings based on away and overall figures respectively, as they each played only one qualifying match.
 
All 22 countries have full team cards with try scorers (a few countries have some extra scorers who scored only in matches not included in the set) and individual goal kicker ranges, separate home and away team ratings, and with separate control charts for home-and-away and neutral venue matches.
 
There are 105 matches that are included in the ratings for this set, and you can either replay all the matches listed on the schedule sheet, or use some or all of them in league or cup competitions, as you see fit.
 
Discounting Wales's winless collapse, the Tier 1 nations were much closer than as been the case for a long time in 2024. South Africa regained their Southern 4-Country Tournament from New Zealand, while Argentina beat all three opponents for the first time, and Australia had a revival in the autumn test matches, including winning at Twickenham versus England, and running Ireland close in Dublin.
 
Ireland retained their European 6-Country Tournament title, but did lose this time - to a late drop goal in London, then split a two match series in South Africa. France meanwhile also were held to a draw by Argentina, and played a test in Uruguay, while Scotland also played a historic test match in Chile, off the back of their World Cup debut.
 
Fiji won the Pacific 6-Country Tournament, beating Japan in the final, who continued with their decline outside of a World Cup, while Georgia retained yet again the 'B' European 6-Country Tournament (seventh in a row).
