My thoughts on this are pretty similar to the first game - it's quite good, but it's hard for me to isolate specifics because my view is somewhat coloured, read Sympathy for Chisa Inomiko.

I will say, a notable improvement over its predecessor is the presence of the final antagonist in the story. Niara came out of nowhere, but sequences like the acid rain and Fomalhaut's raid on the Diet building are extremely memorable.
