This is a way to show people a really awesome RPG, without the need to discourage anyone by stuff like Infinity Engine, used in Planescape: Torment or Baldur's Gate and Icewind Dale series. There's nothing wrong with this engine, but I'm afraid that younger people could be thrown off by the archaics of it.
Anyway, to get back on topic, I urge you all to play some Star Wars: Knights of the Old Republic. If you haven't played it before, you're in for an adventure of your life, if you did, there's nothing wrong in playing it again and reliving the joyous moments.
Why should I play it?
KotOR is a masterpiece. It is ridiculously good. You get a cool story, several ways to do each sidequest and the best NPC in any game to date: HK-47. Seriously, this game would be awesome even if just for him. Just look at this line of his (one of very many such):
"Disclosure: I am a versatile protocol and combat droid, fluent in verbal and cultural translation. Should your needs prove more... practical, I am also skilled in highly personal combat." - HK-47
There is so much to this game compared to the later RPG-like titles... Characters, their stories and interactions, some truly epic quests on the way etc. You're really missing out if you won't at least try it.
Does this game have any flaws?
Sadly, like basically any human creation, this one is not rid of flaws. They're very minor though, the biggest being some skills losing importance (security comes to mind) due to the door-bashing mechanic. It was remedied in the second installment of the game, but even more flaws are in there (they rushed KotOR2 too much to release it during christmas which resulted in the game being not finished and not polished enough, with some lingering bugs remaining).
It doesn't have much influence on the gameplay though, as the most important things happen during the conversations and of course combat (no bugs there at least). Exploration being a bit unfair (since the least combat-capable class doesn't really need one of its core skills) doesn't diminish the overall awesomeness of this title much.
First try running the game without this, if it doesn't work go here:
Some general tweaking, tips & tricks for those who like to fiddle around
High quality music and movies for K2:
Note: They're all of cosmetic nature (maybe except TSL restoration...), nothing that has influence on gameplay as not to destroy it for you.

Ultimate Sound Mod
This one changes some sounds like blaster fire and saber swings to the ones in the movies. Much nicer.
Movie Style Saber Re-Texture
Makes your lightsaber flicker and all...
Both of the above mods work with KotOR I and II (just extract the files and put them into the Override folder in your game directory).

Heroes of the Old Republic mod 1.5
This mod changes the saber hilts. It also adds armored robes to the game (they look great and aren't all that OP).
Use this mod before lighsaber retextures posted above, then just overwrite (retextures only change blade colours and add flickering so they don't brake the hilts). Together this mods make lightsabers look truly amazing.
Since it also gives you access to the lightsaber before the intended time in the game (you find one in your quarters when you board Harbinger) it is not recommended to apply this mod during your first playthrough.
It is fully compatible with TSLRCM 1.7 (which should be applied prior to HotOR).

Please don't blame me if K2 mods don't work as they should, there's a lot of files in them and the process of applying them can be quite tedious. I really tried.
