The first Jedi Knight game (which somehow managed to pass under my radar back when it was first released) has a very dedicated fan base, and one good example of this is the Enhanced mod with among other things replaces the Sith engine's blocky original 3D models with some noticeably less abstract ones.
(Please note that the graphical glitches are due to compatibility problems with this game on modern computers. For many users with advanced 3D cards the game is almost completely unplayable, but luckily I only have to deal with a couple of comparatively minor effects-related issues).
