(Ah, the memories... I've been maping for this game quite some time...)
It was a really fun game - untill it was removed from "zone". What is it like? Well, with four players and more, it's total multiplayer havoc, as the mp-levels are mostly small in size. I always liked the weapons but the force powers are the really interessting factor, I think. I didn't like the saber battles that much, but these were ok, too.
If you want to try it out, I suggest you get the expansion pack, MotS. It has much better (and much more) multiplayer maps.
Oh, and be sure to visit over
here. It's maybe the one remaining JK material source.
