They redid her face, tons of lighting across the gameworld, and re-recorded tons of voice acting. I think maybe they also redid some motion capture. The original faces and animations were memorably pretty awkward. I read a bit from a developer suggesting they learned lots about what they would have done differently, so they did that.
As a huge fan of the original though, I’m hesitant to ever touch this since they changed so much. It’ll feel like some ripoff or something. I find the original a gem, with flaws and all. Every game has flaws, and that’s okay.
It feels like those creators who can’t just leave their music or movies as it was and keep fucking with it.
At some point, you need to let your art be what it is.
