I don't think this was discussed and I think it's of utmost importance for the AOE gameplay. I've seen one or two SC players criticizing AOE for having RMG (random map generator) which can result in unfair maps for some players. However, this is what defines AOE and part of what kept it going for so long feeling fresh, where every game plays differently. AOE doesn't want to be SC or some other game with static maps, a very important part in the game is reading the map and adapting.
I also wanted to stress the important of the RMG since Relic doesn't actually have any game with a RMG in their CV. I hope this will be their first one. AOE wouldn't work without having the maps created through a RMG.
