What hurt it was the over compression of the voice samples (which weren't that perfect in the Jp version to begin with :P) as well of the change of some of them, and i don't mean the changes to Spiral Drill to Cannon Drill, i mean that they change Sagat's voice sample when he throws people with the old one from SF2 world warrior!, or that matter, Ryu & Ken share the same sample when they throw people but in different pitch, and that the voice samples of Ryu, Ken, Chunli are OVERLY compressed, seriously, Chun li sounds manish in the US version, and Ryu like a monster.

they also have lower volume if you know what i mean.

Call me nitpicker but i was so used to playing the japanese version because i used to have that one, and i was very young to adapt to the US version that i rented back when i was 10.
