actually the negotiating between players is terrible. theres a minimum bid that goes to the troll under the table in some shady room in some wopwops (dat be kiwi slang for town in nowhereville). the cash amount is set to rise for every token near base value. so its not really negotiating between managers until you can actually get rid of the middle man
in the mean time i call it 'selling your soul to the devil'
sure i get this literally nullifies higher levelled players giving away deadweights to lower levelled players that are converted to superstars, but at least balance it a bit
