Let's make my point about this:
Basically, it's just a matter of choice. In both games you have some freedom to do certain things. In Deus Ex, it's an action freedom, you can basically choose 3 paths to do things like opening a door, manage your way into a base, ... while it's a dialog freedom we have in KotOR where you can choose to say and consequently to do (because saying something like "I gonna kill you Sith scum!" will certaintly end in a fight) something bad or good and perhaps more neutral. You've certaintly noticed most of the KotOR quests can be solved to get DS points, LS points or no Side points at all, like it's possible to kill Anna in the 747, in the metro station or in the UNATCO Headquarter and in the last case, you can even use her killswitch word in Deus Ex. Gameplay wise, it's very similar, and in both games, it's not very difficult to play them at least 3 times to see most of it's content without having the sensation you know them by heart (which I had in Invisible War while finishing it for the second time...).
I think Warren Spector noticed this in an interview and noticed the manicheism of the game 'KotOR) too, so this poll and assertion don't seem me stupid or laughable at all.
I hope this fundamental gameplay element will stay in KotOR II.
