I've always been a board game fan, and I especially have a fondness for chess variants.  When my love for Star Wars and chess cross, I find myself fortunate that Star Wars has a chess game: Dejarik.  In high school I tried to invent rules based on the movements shown in ANH, but I never got far.

Several years ago, I found these rules.  Quite frankly, they're rather lame: all movements were based on an inherent number of steps each piece is permitted to take in any combination of directions, and it relies too heavily on luck.  But at least it was something.

A few years later, I found these.  More interesting, but rather basic, as all the pieces moved in the same manner without variation.

As you can see at the second site, the author was writing "advanced rules," but they were not completed.  These were supposed to allow for piece variation, but these rules have been forthcoming since I discovered them in 2007.

But I actually forgot all about this game for some time.  I wrote the author of this page to ask how his rules were coming along, and he told me they were actually done, but only in French.  He suggested I translate them, but I don't speak French, and the online translators are obviously quite limited.  I have here the rules in French he provided me.  I don't believe he would mind if I put them up, since he told me to translate them into any language I knew so he could post it all on his site.  If any French speakers wanted to translate this so we all could enjoy the game, I think that'd be awesome, and in turn I could offer him that translation to post at his site.  Hopefully he's still around, since he sent this to me about four years ago.

I hope someone would want to take a stab at this so all can enjoy it.
