and that is why it needs a cleanup.
it has the fundamentals, but it was clearly rushed and you can feel the tumultuous development it had... starting out as a GameCube game, then getting developed decently far on the og Xbox, finally being pulled over to the Xbox 360... it was crazy.
they couldn't even fully rid themselves from the original celshaded artstyle, as the characters still often look like weird cartoons set against a hyperrealistic environment with high detail (for the time) textures.
if they adjusted the artstyle of PDZ, improved the controls, and changed a few of the levels a tiny bit, it could be amazing.
some of the changes could be similar to what Eidos did with Deus Ex Human Revolution when they released the Director's Cut... adjusting all the things that just don't fit right.
