End of Nations promised a truly massively multiplayer online RTS game. It was a game I was excited for, even though I knew my PC at the time couldn't run it.
The backstory and setting of the world had some undertones of Biblical Antichrist world government end time shenanigans. You played as one of the many groups trying to take it out.
Unfortunately, it was first turned into a MOBA game and then got totally canceled after some layoffs.
