This set should have everything you need to playtest a game of Star Wars: Legion. You will need to provide miniatures (of course) and a set of 8-sided and 6-sided dice (I have 12 of each color).
I suggest you print the cards and place then in card sleeves with a regular card behind it. The dice stickers are scaled for dice that are 15mm to a side; scale appropriately for your personal dice. The order tokens have a unit symbol sticker that goes on the front side and a faction symbol sticker that goes on the back side. I used Avery opaque full-sheet shipping labels for printing my stickers.
The movement rulers print in two parts and just snap together -- they should still be free to move in the middle. The range rulers have a small built-in support piece for the peg; just snip that off after printing. You should not need support material for any of the 3D printed models.
The ruleset is current to what we know so far from demos and interviews. There are still four rules that are unknown. The ruleset published here has some proposed "house rules" to fill in those gaps. I will try to keep the rules document updated as we learn more.
