Neogaf did a comparison between the two games, and it seems that the extra features, storyline, and improved difficulty settings weren't the only thing that changed in this "Port"

The game also runs at a steady 60FPS with a higher Native 720p resolution (please embedd)

Wow.

I had no idea that the difference was that large.
Sigma 2 has sexier grounds/street lights/doors confirmed!

Wow that looks like a drastic change, but honestly, ppl didn't expect this? It did come out a yr later so...

wow huge difference.
they did huge alot of that blu ray space.

So the old game took place during the day and featured a man dressed as a ninja, and the new game takes place at night and features a scantily clad Soul Calibur auditioner?

Hey, she's already in DOA!

Oh sorry. I couldn't tell because her boobs weren't jiggling in the picture.

It's alright. You're forgiven.

You know, if you don't feel like contributing to the thread you could just not post.

And yeah, the area textures do look much better in NGS2. 

those images are hard to go by as in one of them, the textures look like high end PS1 games textures

Was NG2 that ugly?
