I just did The Void on Saturday at the Venetian and let me say as a huge Star Wars fan who's collected 10's of thousands of dollars in toys and memorabilia, has been to conventions and has seen all of the films a ton of times since 1977 I am hard to impress. I have to say that this time I was VERY impressed!
I won't go into any spoilers or details about the game as you should experience it as it happens and not by someone else's account. I WILL say that it is an excellent use of 30 dollars and it won't be like any Star Wars experience that you've been through before. If it can blow away a die hard fan like me I pretty much guarantee you will enjoy it regardless of your level of fandom (my girlfriend was blown away by it as well and she's a so-so fan).
My only request to the makers of the experience is to add more and more missions as I would happily go on it multiple times in a day if they can rotate me through different experiences.
If you are curious enough to be looking at reviews about The Void I say go for it 1000%.
