I’m not much of a ladder player and mostly stick to playing Overwatch competitively online.
However, when I do play Age of Empires, I tend to stick to Skirmish against the computer and campaign modes.
From what I’ve seen on this subreddit, it seems that the map Arabia is the most popular.
Because of this, I sometimes choose to play on Arabia to improve my skills.
However, my personal favorite map is Black Forest because it allows me to focus more on defense and resource gathering rather than immediately building up an army.
Additionally, I prefer the aesthetic of a more verdant map rather than the desert terrain of Arabia.
