The main focus of JA is the lightsaber combat, which itself is awesome. The slow motion effects, the cool acrobatic moves, the blur of the lightsaber as you cut apart enemies was very fun. This is pretty much the core of the game and I think the purpose the developers had in making it.
It sounds like you guys wanted it to be like KotOR, which would have been cool in my opinion, but that really wasn't the purpose or intention of the game.
If you want a game like KotOR, just play KotOR.
If you want to go all out in a lightsaber melee play JA.
If you want to play a good fps with a decent storyline and great levels play JO.
