[Kamaeru]

Just copy GTA some more. Give the availability of things like helicopters and tanks but make the price ridiculously high, so even the richest players will feel poor if they buy it. Easy, done, problem solved, get to work. Also, there is nothing wrong with players having more money, but it means the value of money is getting low. If longtime players are able to easily get money while new players are able to only get a little at a time, you have to raise the amount of reward for easier jobs. If you don't like it then it is your own fault and responsibility as developers for screwing the economy up, not the players, so stop blaming them. The problem with the imbalanced gameplay cannot be permanently solved using a reset.
