One of the best games I've ever played! Instantly recommended.
The multiplayer has lots of game modes but needs a bit more variety. Multiplayer doesn't have much servers up since it's a very old game but playing with bots is as much fun as playing with actual people and trust me it's HEAPS of fun either way.
The single player is very good. You play as Jaden and instantly you meet Rosh and he eventually becomes a really good mate soon after. I don't really want to spoil much so I'll just say the single player is the best I've played in years and is fairly long. A few annoying puzzles like jumping puzzles may frustrate you but at least it has a quick save option. I didn't find the puzzles too annoying but some did make me rage a little... or a lot. The graphics aren't different from Jedi Outcast at all from what I know but are still very good, well for the day anyway. Lip syncing can be a bit out of place and animation isn't too good either and the characters look like robots since they have almost no facial expression ever. You will meet some familiar faces such as Chewbacca, Kyle Katarn, Luke Skywalker and some wonderful Rodians as well as a lot more. The Jedi forces haven't changed a bit since Outcast and there is no 1st person lightsaber view either. But there is still 1st person with everything else unless you manually change it your self.
Jedi Academy is an instant classic. Get it if you can find it or get it on Steam for $10. I give this game 9.5/10. I only took away 0.5 because the graphics barely changed and a few bugs and puzzles are annoying and also characters have no facial expressions but a lot of people may not get bothered from these. The only thing that really annoyed me were the puzzles but the other stuff were just small things.
