I'm not going to put any images of the database itself, and how awesome it is. Because FM26 is one of the most un-photogenic games of the year. But I will outline the changes, and hopefully it's enough for you to play it.

92-Team Premier League

• Teams start in one of four groups of 23: North West, North East, South West, South East, based on their position in relation to the city of Derby.
• In that group teams play one round of fixtures, home or away against the other teams, a total of 22 fixtures; After playing those games, the top 6 teams in every group qualify for the Championship Groups, the middle 12 teams in every group qualify for the Classification Groups, and the bottom 5 teams in every group qualify for the Relegation Groups.
• In the Championship Group North and Championship Group South, two groups of 12 teams take 100% of their points, and play one further round of fixtures, home or away. The Top 6 teams in both groups automatically qualify for the Champions Playoff. Teams from 7th to 12th in both groups qualify for the Wild Card Table.
• In the Classification Group North A, Classification Group North B, Classification Group South A and Classification Group South B, four groups of 12 teams take 100% of their points, and play one further round of fixtures, home or away. The Top 3 teams from the four groups automatically qualifies for the Champions Playoff. Teams from 4th to 12th in all four groups qualify for the Wild Card Table.
• In the Relegation Group North and Relegation Group South, two groups of 10 teams take 100% of their points, and play one further round of fixtures, home or away. The Bottom 4 Teams in both groups are relegated to the National League. Teams from 1st to 6th in the both groups qualify for the Wild Card Table.
• At this point, teams have played 31 fixtures if they're in the Relegation Groups, and 33 fixtures if they're in Classification Groups or Championship Groups. It is at this point, that the best placed team overall wins the Premier League Fans' Shield; A Silver Plate recognising them as the highest ranking team before the Champions Playoff begins.
• Before the Champions Playoff begins, all off the 60 teams that have been sent to the Wild Card Table are ranked based on their season so far, in a North and South Group of 30 each. The Top 4 placed teams in each of the two groups take the final eight spots available in the Champions Playoff, taking the participating teams to 32.
• Those teams then play the end of their season, the Champions Playoff, to decide the Premier League champions and to allocate European Spots; Progressing through the First Round, Second Round, Quarter Final, Semi Final, Third Place Playoff and Final. The teams can play a maximum of 38 fixtures. The Champions Playoff is played entirely in a Major Host Nation.

96-Team National League

This is actually easier to explain. Teams start in one of four groups of 24: North West, North East, South West, South East, based on their position in relation to the city of Derby. They play Home and Away, for the usual 46 fixtures. The Four Groups then each have their own playoffs in the usual National League Promotions Playoff. At the same time, the four teams who have topped their divisions and already won promotion to the Premier League play in a Semi Final, Third Place Playoff and Final, to decide which team will take the National League Trophy home. These games are played at the Four Home Nations National Stadiums.

Fantasy Changes

Other than the obvious, there are other fantasy changes, outlined below.

• The Premier League has roughly another £90-120M in money across a season, which I think is realistic, since they are no longer paying Solidarity Payments to the Championship, League One and League Two, because they're all in their division.
• The 96-Team National League does have Prize Money. The combined amount teams can earn as a maximum is around £4M. Roughly £1.8M in Prize Money + TV Revenue if the team topped their division and won it. Plus around £2.2M in Solidarity Payments.
• All Cups have updated Prize Money to align with the fact that a lot of competitions have more stature now E.g: the Vertu Trophy is now technically a Top Flight competition (but its still set so the same types of clubs would play in that competition and roughly the same Youth Teams), the Prize Money in the Final is around £960K, instead of £100K-ish. The only really large increase is in that the FA Cup and Carabao Cup are up from £2M and £100K (Is it really that low IRL?) to £11M and £8M. But with how compact the English Pyramid is now, it feels necessary.
