I'm making some uber changes to Minas-Tirith, and you should see an Alpha within a few days. It's a rather simple map with awesome execution.
Here are the stages:
Make the terrain have depth: Done!
Place units: Done!
Scratch the units and all the triggers done thus far: Done!
Make the terrain twice as good: In progress
Replace the units strategically this time: In progress
Restart Triggers: In progress
Breath life and make a cinematic experience: We'll get to that after the basics are done ok?
I could go dig up my old thread on it somewhere... from like a year ago.
