GameZone has posted a review of Samurai Empire, giving the Ultima Online expansion an overall score of 7.5/10. Their conclusion:
UO: Samurai Empire is a nice expansion that gives the UO community more opportunities in terms of crafting and guild matters, but while it offers new lands, the game itself has not really changed direction all that much. Is this a bad thing? Absolutely not. The samurai and ninja are fun to play. The game treads new ground but much remains the same. UO is the granddaddy of online gaming and with expansions like Samurai Empire, it still has life in those aging legs.
