what i've done in my db, is to give all the rb teams about 6000 reputation.
i also gave them max attendance so they quickly do plans for new stadiums
not very sure about giving everyone a sugradaddy, will make them giants pretty fast
i think the pre-season tournament could give them a lot of prize money
in my opinion there shouldnt be 2+ rb teams in any league (like leipzig and newborn berlin for example) (did it in my db, because i included the british isles mod, so i ended with 4 rb teams in the same division at some point. lol. (york, edinburgh, dublin, belfast)
the summer tournament is quite tricky tho, hasnt worked properly for me yet
