Okay! A few more questions came to mind, so I thought I’d ask… Can we contribute to this project? Is there a playable or downloadable demo available?

I could use some practice in animation... I improved the Run-animation, if useful I can continue animating. (were should I upload the files?, here?) 0.A.D Body Meshes And Animations.002.zip

Art must not die. It's incredible that they knew Rome was colorful and didn't paint it. The world's largest outdoor set.

Someone should pick up that patch again.

"Realism" doesn't make a game better, it's just that maybe the last 10-20 years this was what people were trained to believe, how else can you sell a new hardware every other year . Some of the most legendary games are from the 80' and 90' after all.  Anyway correct wall physic is computationally much more expensive, and if you do it with walls why stop there. How about buildings, trees or terrain? You see were this is going. Lag is always much worse then some bending of realism.
