a careful player dont lose money because of death, i am never have money on me. because there is one atm in every city and you can easly get your money when needed. so buying things that are legal with credit card would be cool. or it can be implemented some form of tax if you use money that was in bank with credit card, so people dont wanna lose money can pay tax. i hate go atm, withdraw some amount, come to buy and see you have 200 $ less while buying a something more expensive. then go to atm back and got that 200$ and come try to buy again.
