It's very easy, but it has a fairly compelling story and it's fun.
Jade Empire takes place in a setting that is clearly inspired by Asian mythology, mostly Chinese mythology. You are a (unsurprisingly) special child, who has been training under a Master known only as Li for all twenty years of his or her life. After you become aware of your somewhat interesting heritage, things are set in motion that culminate in an epic adventure. How cliche. Regardless, the story in Jade Empire is told very well, and takes a few twists and turns along the way. You also get to choose what your character says most of the time like in past Bioware releases. You don't always get a choice, and often your dialog choices do not amount to anything, but it's still a nice feature.
Jade Empire is very different from Bioware's past work. Instead of utilizing a semi-turn based battle system, Jade Empire is entirely real time. You can select from a variety of fighting styles (you only start out with one), and then you attack enemies by moving up to enemies and whacking them repeatedly, it's simple enough. Since Jade Empire is an RPG, you also have to keep your stats in mind. Leveling is done the same way it is done in most Western RPGs, once you get enough experience you put some points into stats and skills. In Jade Empire you also don't have to worry about upgrading equipment. If you want better weapons, put more points into your favorite fighting styles, because that's the only equipment upgrade you get. There is a gem system that allows you to add some bonuses to some base stats, but nothing significant.
Graphically, Jade Empire is a fairly beautiful game. There is a great host of wondrous environments, though they are very linear. Some of the minor character models are poorly done, but the important characters are excellent. Most enemies are also very well designed with fluid animations.
The audio is exceptional. The voice work is mostly top of the line (with the occasional bad extra). The music is fairly popular among the fans, composed by Jack Wall (Who also composed the award winning Myst III: Exile and Myst IV: Revelation scores) it's a symphonic score that catches the Chinese Mythology settling very well.
Jade Empire is a bit simplistic, and seems to cater to people looking for fast action. There's no real tactical combat, and you don't really need to use the currency for anything (In fact, I never used my Silver at all) since there's no armor or weapons to upgrade. It's an RPG that places emphasis on fast paced action and story telling, and it both excels and suffers because of this. I still recommend it to any RPG fan to try out for themselves, it's not as exceptional as Bioware's earlier releases, but it's still worth playing.
