Imperator: Rome actually. I think I’ve been seeing a bit more appreciation for it recently (or maybe I’m just imagining it), but the launch was really rough and none of the updates, which changed quite a lot, really got the player counts up until Paradox just decided to abandon it. It’s definitely flawed, but I have kind of a soft spot for it and still enjoy the occasional game. For me the army automation was really nice, since microing stacks has always been one of the most annoying things for me to do in these games, the pop migration and stuff helped it feel like my cities were really growing more organically, and where the basegame falls short there are still some pretty decent mods to improve things (one major mod is actually still being regularly updated years after the game was axed by the devs).
