    Millennia is a grand and demanding 4X strategy game that caters to players who crave complexity beyond Civilization. Its deep resource management, alternate historical ages, and massive scope create a rewarding experience for dedicated strategists. While AI shortcomings and shallow diplomacy remain issues, a year of updates has turned it into a polished and engaging title.

    Millennia is a good turn-based strategy experience that has the potential to become great after some updates and, possibly, expansions. The core idea of alternate historical ages is engaging but needs to be expanded on, with more options and more interactions. The rest of the mechanics are familiar but have just enough tweaks to keep turns interesting. The combat sequences need to go and the title should expand its diplomatic elements and trade system. The development team is planning to add modding support before the end of the year. Millennia isn’t a revolution for the 4X genre but has good ideas, even if they aren’t always matched by the execution.

    Millennia is the most serious competitor of the Civilization series since 1991.

    Despite its flaws, though, Millennia’s gameplay is compelling enough to keep me coming back. It’s better than Humankind (which I say as an unapologetic Amplitude fanboy), and on par with Old World, but it doesn’t quite dethrone Civilization. However, its introduction and implementation of new takes on genre staples puts the ball in Firaxis’ court.

    Millennia starts like Civ, but offers good mechanics such as alternative eras and construction sim elements. Weak AI and graphics.

    A genre diamond in the rough that unfortunately still suffers from balance problems and strange decisions, but could definitely blossom into a real Civ 6 alternative.

  1. The biggest miss, for me, is the Ages system, which feels like a solid concept that desperately needed more time in the pre-production concepting stage to make work the way it was intended. Pivoting to fantastical alternative eras of history could have made for a wildly exciting story with each campaign. Instead, it far more often ends up feeling like a compulsory family road trip to somewhere you don't want to be, while you pass the hours half-listening to another podcast about the Roman empire.
