okay, so i improved my playstyle a little bit (using the Iberians at first since i like to play defensively until late in the game). now, my mention of Petra being too aggressive earlier, i think some of the big things that the 0ad really needs, but which would definitely be closer to the bottom of the list, are some aesthetics: resources should look like they've been worn down over time depending on how much of them has been gathered, and buildings should have visual indicators that they're damaged--at the very least, it could be fire coming from them like in Empire Earth. the only other things i would (currently) recommend is that trees are knocked down when you start gathering from them, like in AOM since it adds some realism to the game, and that thickets of trees should be mostly impassable, with some civs having special traits allowing them to navigate forests. while i understand the reasoning behind trees being passable, i think it hurts the game on a strategic level. in my most recent game, i had a defensible position with lots of cliffs around my starting point, but because trees fill in alot of the valleys leading to my base, i can't build walls to block off those routes and fully exploit the defensive position without knocking down an entire forest first
