Hyperspace, eh? You looking to complete the Kessel run in under 12 parsecs?

I don't know much about Earth's galaxy, but I know a lot about a galaxy far, far away. I also know a bit about the Milky Way, but not the one as we know it. I'd like to say I'm related to Commander Shepherd but I'm afraid that wouldn't be true. I did help destroy the Reapers though :p

You should check out DealExtreme for their mini key chain lightsabers. I ordered a BUNCH for my wedding. We had them as party favours. People also waved them around, lighting them up, when they wanted Frank and me to kiss. Those could be pretty cool. There might be some other colours on Amazon too.

Something like this: https://www.amazon.ca/Uncle-Milton-Star-Science-Lightsaber/dp/B00339NPFW/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1511082466&sr=1-1-catcorr&keywords=mini+lightsaber

Alternately, you can also buy glow sticks from the dollar store and add little DIY cardboard bands to the ends, painted, or crafted more elaborately, as you see fit, to make it look like lightsabers. That might be your least expensive option.

If I had lots of money, I would hang a bounty on the wall lol Nothing says Cantina without a Kowakian Monkey-Lizard either, but hey. If you want to go all space and Cantina-like, SWTOR has some awesome Cantina songs from its soundtrack. I've got them all, could send them to you, or you can find them on YouTube (SWTOR Cantina Songs/Music).

If you can Cosplay, that would be fun, have some space folk walking around, some aliens, some Jedi or Sith, perhaps people from other galaxies.

When people order something or walk into a room, or from time to time, you can have droid sounds on the speakers. Like R2-D2 sounds.

Of course, that's the direction I would go in. I even own my own Sabaac deck. Having a few of those, could make some fun games. We use dice in this galaxy, because we don't have droids for the random factor, but throw in some drinking alternatives to the game and you've got some pretty fun times ahead.
