Do you have a number for "that many enemies"? If article is giving one, I couldn't find it. There are plenty of modern games that is multiplayer and supports enemy numbers that I would consider "massive". Or massive number of players if that is that matters.
I played it last night. There would be maybe a couple dozen enemies on screen. Which, for a dial-up connection, is a massive amount to communicate about in real time. The fights are structured such that it feels like 5x that amount, though.
