Someone on KS hoped PE would have a complex economic model. **** that. Something simple. and YES in some way or shape in form i guess linking it with difficulty (loosely) would be good (if there were other options to do it then great as well). Quite a few games get spoiled when you can pile up lots of money but ending up with nothing to spend it on because items were either too cheap in the game, or too easy to make money, or the loot drops were too good and too easy to get without needing to buy.
