Well, are you?
Just because someone owns something doesn't mean that he is involved in everything that is done.
Bill Gates isn't developing software for Microsoft, just like the owners of Walmart, IKEA or any other billionaire don't have anything to do with the business of local parts of the company.
Lucas is a film-maker, he produces movies, not to mention that he is father of three children, he has no time to lead companies like LucasArts, ILM or Skywalker Sound. Every sub-company has its own management which makes the decisions. Above them, is another management which makes sure that all the managements of the sub-companies are doing their job properly.
That is a fact. Just because Lucas gets involved in certain production circles which require the word of the creator of Star Wars, doesn't mean that he is involved in day-to-day business. Why do you think these people are around, because Lucas likes to throw money at people while he is doing their job?
What kind of movies ILM and Skywalker Sound are working on, and which games LucasArts is working on, is decided by themselves. The president of LucasArts decides how to handle the franchises they have. He decides what kind of release schedule they want to have (see the change from many games to just one big game per year that they were talking about), whether they are producing in-house or outsourcing the material, and which games have a high priority.
How exactly does breath control work? Does it filter the air to make it clean or does it just make it so you don't have to breath at all? From KOTOR 2 it sounded like you didn't need to breath anymore. This makes me think Qui-Gon and Obi-Wan were using a different power because they had to use those weird little devices to breath underwater.
Pretty much the only Star Wars game I've played beyond KOTOR 2 have been Jedi Outcast which also had speed and Battlefront which allowed Jedi to run super fast, so i assume here that speed is a pretty common power throughout history.
What you really need to do here though is compare the magnitude of certain powers. In the movies we see Palpatine using lightning on Luke and it doesn't look too impressive. In KOTOR we have characters who hold up one hand and shoot lightning everywhere, killing all the enemies around them.
Bastila's battle meditation. She had the power to augment the power of an enitre fleet. We see nothing cpmparable to this in any of the movies.
Also, all the characters in KOTOR are way stronger than anyone in the movies. In the movies when someone is hit once by a lightsaber body parts usually fall off. In the KOTOR games it takes like a hundred hits with a lightsaber to kill someone. The old Jedi order obviously had some lightsaber resistance abilities.
If I remember correctly the Republic started winning some serious ground victories after the Jedi became the Generals. Battle Meditation? Maybe.
It all goes back to the game/movie argument. In games, people want Epic powers. In movies, you tend to stay away from a big red/orange death beam connecting a Sith to his victim.
You've got it twisted... Look at "Transformers" they butchered it to make it more mainstream.
