way too long to upgrade anyone to any sorts of usefulness! been playing very slowly over the years and still can't figure out half the things to do in this game. it's very complicated to figure out how to upgrade each character correctly. and if you make a mistake it costs actual money to fix your mistake or you loose the items by destroying them rather than exchange them for proper items. not too mention there are some modes on this game not available to the average player. only for whales.
