heavily

So in the last week I thought to myself what I want to play and I concluded that I want to play another JRPG. I really loved Xenogears and Chrono trigger. I am looking for something more like Xenogears - complex, with philophic concepts(not a must though, its not that common), full of twists...

I am looking for a heavily plot based games to play - examples would be the force unleashed series and Batman arkham series. games like kotor can get in the equation as well. so please RECOMMEND ME! Do not mention mass effect please.
