There's now a poll running on this site that poses this question;

Should the EU galaxy ever know peace?

And here are the following options and results (at this moment):

Yes. Let's have a happy ending: 29%

Yes, for a time, but don't publish stories about it.: 22%

No. It is Star WARS, after all.: 49%

A majority of fans who answered this poll want more conflict in the Star Wars galaxy or at least, they don't want to see the end of it. Well, that's only natural. Without the backdrop of war in all of the Star Wars movies, the story wouldn't be as captivating as it is. Juxtapositioning internal struggles with the galactic struggle is what makes Star Wars so beloved. Its epic yet goes deep too. Naturally fans would want the same feeling in the books, comics, games and so on.

What the franchise must be careful with is not to get stuck in creating a neverending series of conflicts. Yes, with conflicts the WARS in Star Wars will be upheld, but that could also harm the series. The risk is that the galactic conflicts and crisis' will eventually be nagging and that the uplifting story of celebrating diversity and overcoming the odds will seems dreary and depressing since nothing will ever be peaceful in the galaxy. It will not be entertaining any more. It will not be thoughful any more. It will only be War.

One of the reason why Chewbacca died was that our heroes had survived so many dangerous situations that the writers thought that the only way to show how grim this conflict was going to be was to kill off Chewbacca and later on other prominent EU characters. If it reaches a point where reading about the characters adventures aren't enough but to actually get a sense of the danger a beloved character must die, then we must take a step backwards and take a look at how the franchise is being used or what we want from it. The movies are matinee adventures and the main characters in matinee adventures survive against impossible odds. That's how those fantasies works and that's what draws people to these kinds of adventures, from the Errol Flynn adventures of the 1930's to Star Wars up to Pirates of the Caribbean. If that element must be lost because fans are "battle-hardened", then that isn't a good thing

That's why I think it's a good idea to jump a few hundred years into the future or a few thousand years into the past and describe those wars and events. It's time to leave Luke, Leia and Han alone. It's time to give them peace. We need to introduce new characters and new events that can captivate us. Knights of the Old Republic was successful in this way, Legacy will most likely also be successful.

That is not to say that we're done with the two major conflicts. We're not done with the Clone Wars. I'm pretty sure that there are several Jedi Generals that have yet to be discovered, quirky Clones to be depicted or Corporate backroom intrigues to spark interest left before we leave the Clone Wars alone. There are parts of the Galactic Civil War that could be expanded upon or improved from those early days in EU-history. There's also a space of time between Revenge of the Sith and New Hope that has potential and which is being the subject of the latest EU works.

I've got another suggestion too: Phantom Menace showed us that a local conflict can work just as well story wise as a galactic wide one. We don't need all-out total warfare for it to be Star Wars. It's the home of several species and I'm sure there are loads of conflicts between various species on various planets that have yet to be explored and that could make the Star Wars galaxy more colourful

As you might gather, I'm not advocating a total stop of any more war in the Star Wars galaxy but what I want is caution in how much war is used. Heck, every story might not need to centre around a war really. I'm pretty sure our EU writer are clever enough to write a Star Wars story where there is no "war" as such, or perhaps doesn't have such prominent place in the story.

I'm sure we all have the creativity to offer one part of the Star Wars galaxy a peace whilst inventing new problems for another part. Don't stop the war, but don't over-indulge in it either.
