So lets look at a well read excerpt from an interview with Raph Koster:
Well, my opinion is Jedi are evil. Heh.
You see, Jedi are an immense attractant to players, readers, viewers. As a kid, I too waved around plastic lightsabers (we kept bending them as we struck one another, I am pretty sure my mom got really sick of buying new ones). Who can resist the fantasy of having this awesome sword, effectively magical powers -- mind control, telekinesis, telepathy, and more -- and of course, the classic Hero's Journey? I mean, it's basically an ideal play scenario.
Except that of course, you quickly realize that by comparison, everyone else sucks. I vividly remember granting Han Solo access to the Force when we played with the original action figures, because, well, he was too cool a character not to have them, you know? (We indicated Force powers by bending the legs all the way backwards, sort of a hip-shattering L shape, and then they could fly!) And let's be honest, how long would Han Solo have lasted against Darth Vader? About two seconds. In fact, Kyle Katarn, the most popular Star Wars video game character, basically is Han Solo with Force powers.
This is all fine and dandy in games where you play a Jedi and mow down Stormtroopers by the hundreds. It worked great in the Jedi Knight games. But Jedi are notably absent from the gameplay of other types of Star Wars games, and for a good reason. They are a discontinuity. They are too powerful. They are an alpha class. Not a problem is a single-player environment, but what do you do with them in a multiplayer setting where some people are badass Han Solo types who will always lose?
This same issue had come up in the Expanded Universe books and stories. You basically have the problem that:
-people identify with Jedi
-they're rare
-they're incredibly powerful
This meant that creators laboring in the universe had a few choices:
invent new stuff as powerful or more powerful as Jedi (which was done more than a few times -- General Grievous, the Witches of Dathomir, the World Razer, a living planet called Zonarma Sekot, The Ones - OK, it was done a zillion times, which just proves my point).
tell stories with no Jedi in them, as in the original Han Solo books by Brian Daley.
Of course, the demands of games focused on Jedi also meant that the powers of Jedi kept having to go up, too! I mean, people actually complained when you didn't start as a powerful Jedi in Jedi Knight II, and eventually, we got to the ludicrous heights of Starkiller in the Force Unleashed games: "sufficiently powerful enough to rip a million ton Star Destroyer out of orbit and slap Darth Vader around like he owed him money."
