Jedi Outcast with all the bells and whistles.
Perhaps the reviewers looked primarily at the single player experience. Yeah, the choose your own adventure style really kinda does take away from the storyline, and not having a Star Wars character as the main character probably hurt things too, but look at the improvements!
First of all, without even discussing the staff or dual-saber options, the single saber (still my favorite) has evolved. The blue style still sucks in duels, but yellow is much faster now, and actually usable in a master duel now. Red is even slightly faster, though I'm not so sure this was a good thing. Now red is powerful, and fast enough that people will use it more in duels. It's also easier to control and activate the special moves. All the moves are easier to use.
This is a huge interface improvement. Now, the staff and dual-saber options bring their own cool new moves to the mix. The dual sabers are primarily defensive, can block most anything except red single, and can activate a saber shield by using the force. With the staff, you get kicks and butterfly attacks. This adds unprecedented strategy to the multiplayer.
The visuals are a step up, with a lot more colorful backdrops and the sounds remain the same. Overall, the designers wanted to focus on improving the sabering experience in this game, and that's exactly what they did.
