well, like the football managers sims, I'd like to be able to start from some extream lower leaque and see how far I can get. At the present, almost all freeagents and transfers listed players are mostly high level international players. I miss having the village team which doesn't even pay its players...like the old days. Plus the fact that you can buy new players every week is a bit to easy. I'd like to see this run like the football games were you have to plan for the next transfer period, buy the odd player and continue. Injuries would also be a thing to add.
I had set up an all canadian Vancouver leaque with canadian players etc...but within the first season, most teams had bought expensive international players...sort of spoils all the work put in. But it is nice to be able to set up personalized leaques though.
Anyway, if you have ever heard of, or played "Blood Bowl" then it has a nice easy way to set up different competitions with numbers of Div's etc. Have a look and you get the idea.
