For my thoughts, I'd just like to say that whilst it's important to remember there are 3 dimensions in Jedi Knight (one of the things that is mentioned by most articles giving thoughts on how to make a good level) it's also good to not let us pursue those 3 dimensions to the end of the Earth. Clear? I thought not.
Yeah, sure, you can get a sector thrust that shunts you x-wards, or y-wards, or z-wards, but what about one that shunts you in the (1,0,1) direction - up and across? Obviously there are many many many times where just travelling in one dimension is desirable, and most appropriate, but let's not forget that you can get away from grid-like structures in your level.
Just some thoughts...flame me if you wish. *Thinks about that* Actually, don't flame. Even if you do want to. Come back with some reasoned arguments instead.
