I got the game yesterday, with bonus disc.
so far i have only palyed the training and first impressions are good. The training is more through and breaks of onto different sections for different areas, such as speedbike and AT-ST. the main free flying area in your T-16 skyhopper though seems to be a much more cut down version of the original.
The third-person bits arnt too bad and the main flying sections appear to be pretty much the same with no real changes though the display is slightly more different.
anyway ill be going to play it more in a bit and will give you more information then.
