I was never a really big Star Wars fan (enjoyed them just wasn't super into them) but spent a lot of time on DFII: JK modding. The cog language could really do a lot if you leaned on it hard enough. The game engine's ability to do absolutely huge outdoor spaces without crumbling in performance was kind of unique at the time. There was a real sense of vertigo for me. I remember having a lot of fun with the cheesy grappling hook mods in multiplayer, flying around and slingshotting around ledges.
