both KOTOR endings also suck a lot in my view.
I've only played the first game, and i would agree normally
Spoiler Alert, click show to read: 
after such a great final level we get a cutscene of our heroes being cheered,(if you chose the light option) which kinda sucks really.


However, how does the first star wars film end? Great battle, lots of boom's, then some footage of farmboy and han being cheered... So in a way it keeps within the star wars setting. Still sucks though, I also was expecting more.
