This is the closest we'll get to watching the events in Evangelion unfold in a videogame I guess.

This illustrates my point.

Xenogears is one of my all-time favorite games. It had a such an amazing story, characters, and soundtrack (even for a PS1). I've since played Xenosaga which was also excellent. I picked up Xenosaga 2 but I need to put some time aside before I start playing. These kind of games consume me once I start.

I can only imagine some Eva type version using the Xeno engine. That would be awesome.
