KotOR II (and KotOR I for that matter) making fun of G. Lucas's ideas?
I don't think so. In a matter of fact, I think it is quite the contrary.
Sure, both games (but mostly TSL) look beyond the simple Light versus Dark conflict, that is the soule of Star Wars. The games deal with topics from the movies like fall, redemption, and betreyal, but I think they have developed them in more detail. Not only that, but because the games are RPGs, the player can(or rather must) choose which philosophy to follow with its pluses and miuses.
The Sith Lords introduces new way of looking into the jedi and sith( due to no small part of Kreia). This is a more neutral or human look to the events. I have seen complaints that K2 does not feel typicly "Star Wars" like K1. However, I feel it is better that way; the RPGs as I view them are to introduce a player in a complex and detailed world similar to life on the planet Earth where the player's choices have a great effect on the story developement.
Just to summorize: The new points of view introduced make SW only more real and human. Wasn't this one of George Lucas's main intentions?
OK, so what does make fun of the guy's ideas. Well, let me just metion the tones of bad books, fan fictions, parodies, comic books, and computer games of which Sw is crowded. Of cource, there are also good ones, but less in number. I am not very familiar with any of these, good or bad (the KotORs are the reason I like SW, but the movies are also nice). Still, I can give an example with the LS ending of the game Jedi Academy. How smart does fighting the soule-of-a-resurrected-ancient-sith-lord-that-has-posessed-a-new-body-and-wants-revenge sound to you? To me it sounds cheeeeeesyyy(mildly put).
