it makes it look more cluttered, grimey and bodged. lol also adds a little more interest with more textures. 2 chains i think were purely for the animation as cloud wouldnt have been able to climb down 1 with the simple geo and simplified animation. I remember him forming this H shape with his arms n legs to climb stuff lol.

On a side note ive just found out that FF7:AC is out on bluray now with an extra 20 mins of footage! Come on payday!!
