This is a fair warning to anyone who buys credits/anything in Urban Rivals.
Because of rampant inflation the value of your purhace DIMINISHES constantly. So even if CURRENTLY you seem to get lot of value with real money (for example getting BM missions done) - in few months or even weeks you will lose the relative advantage. This does not only concern in-game clintz but it also concerns value gained trough spending real money.
For example, the relative value gained from spending money to UR has made 10$ purhace half a year ago be currently only about 2$ worth in currently usable resources. That's how you lose real money value on UR. In maybe half year that 2$ becomes even less in effect.
This is not a word against UR or Acute Games, just fair warning about how the ingame-commodities inflation works also regarding real money.
