I look at Star Wars, and the game translations, from a established law point of view. Yes, it's true that the force can be used to lift objects, in fact bigger than the person using the force. Then by deduction, force users should be able to lift themself - in essense, they should be able to fly. Yet none do. They use the force to jump higher sometimes..yet even strong users never fly or stop their descent.
Hell the Emperor and Mace Window both were killed by falling, and they were much stronger than some no-name sith wannabe.
So I can't just explain a force user jumping high up, stopping mid air, and slashing around - as it's against established powers that would have been used.
Furthermore, that action doesn't eat up your force meter, which shows it's not a force move, rather a physical move - and... well, now we're just back into the realm of bad gameplay mechanics.
Also the light saber feels so damn weak. There's no satisfaction killing people with it, only robots. It won't damage the environment at all, not even the doors you're supposed to break open. It doesn't slice people up at all. It's not even good to one shot the normal troopers/rebels.
Then there's the difficulty settings. Even with the neutered light saber, it's still too easy on the hardest setting - while the medium setting at least feels a little more "right" by letting you one shot people with the lightsaber, it's too easy.You have to go take a piss without pausing or something to die.
