Erm... Why the assumption that you finished those games before I even heard of them? I bought those games when they first came out on PC, so unless you got them before the release date, you probably did the worst assumption ever in there.
Actually to me, while having a good story, Mass Effect is on par with what KOTOR achieved, but that's besides the point. You're comparing a medieval setting with a sci-fi one, scenarios and settings that have different evolution paths in terms of what can be achieved in history, characters and most other things.
Oh, and by the way, I started PC gaming while it still had the old DOS in orange letters, with games like Indy 500, Stunts, Arkanoid and the such, in case you're wondering where my pc gaming background comes from.
