I still remember my first playthrough as it was yesterday. Except that it happened more than 20 years ago when the game was released. It's one of the few games that leaves a mark with its impact. It's as memorable - or maybe more - as Doom, Quake, Half Life and other major titles of the late last century. It's one of the few games that can send chills down your spine and sometimes makes you gasp for air. It's the perfect combination of FPS, survival horror and RPG with its advanced story telling, character development and sometimes brutal action. Even though the graphics will appear dated by today's standards, it's a game that everyone, who likes the first person genre, should get and play. I'm almost sure you won't regret it, it's really that good.
I've been playing a lot of these games, however, StarWars themed or not, this one is one of the best RPGs ever made, period. It plays in one league with classics like Baldur's Gate or Planescape Torment and among all the Star Wars-themed games, this and its successor are on top of all others. Excellent story, interesting characters, top notch dialogs, a solid combat system and generally favorable game mechanics make KOTOR a unique experience. Plus, you get many of the iconic locations from the movies and, of course, a light saber :) A must for a Star Wars fan and a highly recommended for every RPG lover.
