When starting a new game, the new PvP checkbox now allows you to enable or disable the participation of other players. We recommend leaving this unchecked if you want to avoid facing armies that are significantly stronger than yours (for instance, another player might have spent all their resources purchasing available armies, among other reasons).
Essentially, whether you prefer to avoid PvP entirely or simply want to experience the most balanced version of the game, there is now a dedicated mode just for you.
Enjoy the game!
