I would have to say that WarFrame is THE perfect example of this...although still [self professed] in beta phase after all these years, they seems to be one of the few companies treating their players right.  Yes, they have micro transactions, but nothing that can't be reasonably farmed in-game.  AND, you never really feel like you are wasting your time farming in WarFrame.  It's always productive, even if you find something you were not originally looking for.  <br><br>Notice how you never hear widespread complaints from WarFrame players?  And to think, this was the studio that everyone turned down to help develop WarFrame.  Ironic, isn't it?
