Oh man I bet you can get doom running in the scenario editor. The new devs may even be willing to enhance it somehow so that you could.
Although I have not really played or watched competitive since The Viper left for Facebook.
I recently tried Aoe II definitive edition. they managed to massacre the UI so much it hurts my eyes... that alone made me issue a refund
also £15 for a 25 year old game. you'd expect it to be better in every aspect at the very least
