It is the sheer inteptitude of Star Wars authors that has let it happen. Kevin J. Anderson may be one of the greatest science fiction authors of the age, but he was the one primarily responsible for turning the Force into LotR and Harry Potter-class magic. Exar Kun's spirit putting a post-DE Luke into a coma? Exar Kun's spirit imbuing Kyp with the power to resurrect the Sun Crusher?
Tom Veitch is also responsible for giving Emperor Palpatine the power of Force Storms (which is completely beyond what I consider to be 'mystical'😉.
The KotoR games are fun to play, but they - like LotF and the Legacy comics - have recycled storylines because the creators are simply too incompetent to come up with creative storylines.
If there's another: "the Sith return in a bid to control the galaxy - and nearly succeed until that one special Jedi foils them" plotline, I'm going to scream.
Timothy Zahn is the best all around author in SW. And, yet, he too overpowers some characters and undermines others. Thrawn can get an extraordinary readout of tactics from simply looking at artwork. Completely baseless - especially when Thrawn doesn't have superhuman cognitive powers. C'Boath being on par with RotJ Palpatine (though this is retconned)? Ridiculous.
And, yet, he made Luke very weak (or more realistic, I should say), in Survivor's Quest. The problem there is, this is set like 12 years after Dark Empire - and Luke has trouble taking out a single modified droideka.
These inconsistencies are stupid.
LotF is just as bad. Lumiya (despite being weaker than suit-Vader) is capable of creating phantoms in the Force that are as powerful as LotF Luke himself. Very, very stupid.
I prefer the old days. When Jedi were just tough.;Luke was pretty good, but not invincible; when Force push, pull, speed, jump, and mind trick were standard and basically it; when everyone feared Darth Vader; when Yoda and the Emperor were too powerful for lightsabers.
Those were the good days.
