I have tossed this idea around to several players and have gotten nothing but positive feedback. I think that it would be great if we had an in game bank!! As you gain more and more credits, you can "save" some up for whatever you want to buy. This way, you are saving up for what you want to buy, but you can still buy things. We could even have option where a percentage of every call gets put into the bank.
So say I wanted to save up to buy a school but I still want to be able to buy vehicles as needed. I would set the save option to put 50% of the credits from every call into the bank.
What does everyone think?
