I agree with you on the MP problems, but the rest no.
Graphic dissappointing? It's not the best, but it's giving the feel of Star Wars. Do you think the graphics of JO are better?! I played Jedi Academy, which have better graphics than Outcast, and on High settings the game looked very bad and my FPS was about 40 and i have Radeon 9800Pro! On Battlefront i playing with 6xAA and 16xAF and the game run smooth.
