Dungeon World

Dungeon World是非常有原始版龍與地下城（OD&D）風格的系統。它採用Powered by the Apocalypse。根據規則書，開始遊戲前您必須有以下幾樣東西：

• A few copies of the basic and special moves
• One copy of each class sheet
• One copy each of the cleric and wizard spell sheets
• One copy of the adventure sheet and GM moves
• Miscellanea such as: pens and pencils, scrap paper for maps and notes, maybe some index cards

PbtA的特色在於使用Move這個可以觸發效果的開關。基本的Move長這樣：When you attack an enemy in melee, roll+Str. ✴On a 10+, you deal your damage to the enemy and avoid their attack. At your option, you may choose to do +1d6 damage but expose yourself to the enemy’s attack. ✴On a 7–9, you deal your damage to the enemy and the enemy makes an attack against you. 其中，When you attack an enemy in melee代表啟動此效果的時機；roll+x代表擲2d6加上某屬性；On a xx代表結果。

通常擲骰效果10+最好，其次是7-9，6-最差。Damage Roll則按照以下原則決定：

• It threatens bruises and scrapes at worst: d4 damage
• It’s likely to spill some blood, but nothing horrendous: d6 damage • It might break some bones: d8 damage
• It could kill a common person: d10 damage

玩家的裝備也會帶來不同的move。
