How is it different from a "pressure to tip" scenario? The implication here is that, somehow, the increase to $70 for games still isn't enough to cover a pay increase for devs, therefore you should tip them to help them out. THATS EXACTLY WHAT PRESSURE TO TIP IS YOU FOOL
Also most games now have micro transactions on top of being $70. It's still not enough to pay devs? And I'm supposed to trust that the tips will go to the devs instead of some corporate ghouls?
