Hello. I wondered what is the difference between the free Book and the charged one ?
Viewing post in Lancer Core Book: First Edition PDF comments
The free book basically contains all the player-facing content - the intro and first 4 chapters (character creation info, missions and downtime, mech combat rules, and the compendium of all the talents and mechs/systems).
The premium PDF contains all that, plus chapters 5 and 6: the GM's toolkit chapter (including NPC mech info and templates) and the lore chapter.
