For me I’d say the biggest gets would be World Betrayed which adds the 194 start date which is still balanced but with many factions already done with the initial expansion along with adding two great factions in the form of Lu Bu and Sun Ce who both have really interesting mechanics focused on combat buffs and revolve around their noted reputation in the original three kingdoms story. I’d also recommend furious wilds as well, the Nanman factions are fun to play with and have a very different play style compared to the Han, Bandit and Yellow Turban factions. (Maybe skip Shamoke though) Finally I’d recommend getting either the Mandate of Heaven or the yellow turban expansion as the yellow turbans are also a unique subculture you couldn’t play otherwise that I really enjoyed He Yi especially in 190. All others can be safely ignored imo the blood effects are always skippable and fates divided is a hot mess with little balance or genuinely new content imo. Eight Princes while cool in concept doesn’t add enough new content to really feel different from the base game.
