[quote name='Roufuss']Mini Review on the differences.
Now.[/QUOTE]
The angle of the fighting is different. No new characters.
Character models and movement seem a little stiffer. My wife thinks they tried to make the characters look more realistic, but failed. Everyone has that really odd shine.
Story mode has been relegated to picking an arena to fight in, then doing the fight. I can't remember any cut scenes in any fashion.
They've added a Street Fight mode, but its pretty useless. Its basically a wrestling match sans the arena, the ability to use submissions, and characters can be launched.
There's also a Queen's match mode, in which the losing player is required to do a humiliating move such as pretending to be a cat or giving the winner a massage.
Online mode is weak at best. I had a difficult time finding a match, even when the game was first released.
On the plus side, humiliation moves are much easier to achieve. I'd like to say they've added a mode where the only way to win is via humiliation moves.
Tag matches are in, though I was never able to find the belts.
After winning the title, a character retains it. So you can continue to fight as the champion, or have another girl do a series of matches to earn a shot.
