*EDIT*
What would you like to see the new engine bringing up after its release? It's supposed to "bring more content than the current engine can support" so I'd like to hear ideas about it! Perhaps even mention what you'd want v5 itself to change up. Just keep it classy! ( no need to get this moved and locked in a closet or something
