I am thinking that it would likely be a very good idea to include a small Glossary at the end of the introduction chapter.
Towards this ends, I would like suggestions on words/phrases to include in this glossary.
Things like
Armor Rating
DEF (Defense)
Attack Bonus (AB)
Player Character (PC)
Non-Player Character (NPC)
Game Master (GM)
Other suggestions are welcome. I will worry about writing the definitions to include, so no need to try to include them here.
