I'm looking for a game that will have the similar weirdness, surreal narrative and visuals as all the wack-shit, mind-screwy anime I like: Evangelion, Lain, Serial Experiments Lain or Angel's Egg.

So what are some games that would fit this description. I heard that some of the Drakengard fit this description but I also heard that some of them have terrible game and even though I'm specifying what I'm looking for in terms of narrative and aesthetic in this thread, I don't want these to come at the expense of the aspect that defines this whole medium.
