Jade Empire was the only Bioware game I could not play for more than a few hours. Mind you, I still think NWN was their worst game; JE at least didn't seem boring or cliched from a setting and story point of view for the 3 or 4 hours I played it.

But the gameplay was just too simplistic and linear. It just felt too much like an action game and I gave it a chance twice and quit at the same point each time. Shame too because the setting was pretty novel.
