I've seen so many chinese MMORPGs set in China, so many Fantasy MMORPGs, so many Medieval MMORPGs, but none that is set in Japan. I feel like there will be a huge opportunity for it. Such as the rule to become the Daimyo, the power struggle between Shoguns, the all out 10000vs10000 Samurai PvP, diplomatic struggle, all that. Total war Shogun 2 isn't exactly an MMORPG, but it has so much stuff and heartpounding content, I want to be a Samurai, travelling Japan, engaging in wars, all that.
Anyone else with me? And if a developer reads this, I WILL PAY FOR THIS GAME. I will throw money at my screen if I ever see this.
