With the AI being more tactical in DE, it would be nice if there is a dedicated mode where you can watch the AI fight each other. Although you can currently do it by setting all players as the AI in random map, the game will only be focused on the first AI player, and you cannot change PoV, unlike in the HD version. A feature like this would be nice.
Well, you could set up a game with other 7 AI and resign right from the start, then spectate how the game proceeds.
Other way around would be to do like you said, but record the game and watch the replay after.
But anyway, this game indeed needs to have the spectating systems further implemented, like you said, it’s lacking features from previous version of the game.
