Sold a copy of this game, and while the replacement of the instructions back into the box may have been an oversight(am yet to look), the buyer claims there are several items missing.
The game has never been played, it was opened and bundled, but was sold on as it was among a few that were never used. Apparently there are also incorrect pieces in the box.
Not sure what I can suggest as what was in the box was left in the box when bought from new. A list of complete contents would be handy. Have offered a refund, which is fair enough, I would be dirty if it happened to me, but I can't explain missing items when none have been removed.
12 team decks (and here) comprised of 31 cards each (372 cards). 31 miniatures. 12 health charts. 4 (or maybe 6, it varies) Quick Reference cards. 2 double-sided combat maps/boards. 1 cardboard "rack" for the decks (useless). 1 six-sided indented die, with stickers. 1 rulebook. Possibly 12 or 18 health track chits. Apparently many, many boxes were shipped without any.
For ease of reference, the 12 character decks (and their associated minors) are:
1) Anakin Skywalker (with Padme Amidala). 2) Obi-Wan Kenobi (with 2 clone troopers). 3) Mace Windu (with 2 clone troopers). 4) Yoda (with 2 clone troopers). 5) Han Solo (with Chewbacca). 6) Luke Skywalker (with Princess Leia). 7) Emperor Palpatine (with 2 royal guards). 8) Darth Vader (with 2 stormtroopers). 9) Darth Maul (with 2 battledroids). 10) Count Dooku (with 2 super battledroids). 11) Jango Fett (with Zam Wessel). 12) Boba Fett (with Greedo). (Always save the best for last.)
I don't know what the laminate sheet is so I can't comment on that. The game has never been played so I can't explain the missing or incorrect items (A similar Star Wars board game released by Wizards of the Coast called Star Wars Miniatures, so I am wondering if the markers you have are actually from that, but I don't know why they would be in there). All I can do is apologise and refund your money if you want to send the game back. I have messaged you on eBay.
