This is all being considered still and no final decision can really be made until I've had a chance to test it out and see how it works.
One thing that will happen is that everybody will be using the same set-up, this has been a feature ever since the challenge started in 2006 and it will remain that way.
While managing a tier 10 club sounds great, you have to consider the restrictions that adding that many leagues will take on the game. To complete the challenge you need to complete an absolute minimum of 8 seasons, with a lot of people completing a lot more (I'm on 20, some people a lot more than that). Adding lots more extra leagues will affect processing time so it needs to be kept realistic and you have to remember that the further down you go, the more divisions there are in each tier. The other problem is that the further down you go, the more sparse the research is. This challenge promotes the research work that our non league researchers do and I want to keep it that way.
Currently, we start playing in the BSN/S which gives us a chance to manage one of 66 new clubs from the three feeder leagues. This means we are loading 7 leagues.
By adding tier 7 (UniBond, Zamaretto and Ryman Premier Leagues) we would be loading 10 leagues instead, giving us a chance to manage one of 132 new clubs.
Adding tier 8 would mean loading 16 leagues, with a choice of 290 new teams.
Adding tier 9 would mean loading 30 leagues, with a choice of 310 teams.
It is still up for testing and discussion but I think adding tier 7 looks the most realistic option. I would love to go down to tier 8 as my local club is in tier 9, but by more than doubling the number of leagues I think it would have a big impact on the speed of the game, which I prefer to be as quick as possible.
