Buy the new starter pack. You’ll also need a couple of boosters just to start. There’s not enough in one starter pack to learn how to play. The game can be played with the new or old figures. Some notes
Old starter packs have old maps with 2" hexes. That is what we play with online here.
New starter packs have new maps with 3" hexes.
There are 4 sets of rules: Orignal, Revised (this added the aircraft rules), next generation revised (this added the new 3" maps), expanded (this one doesn’t come with any starter packs, its bought seperatly about $20, comes with some extra maps, has some extra “expanded rules”, the expanded rules are very complicated and not used by anyone I know who logs on at this web site, also adding that for $20 the book is made like crap)
