D100 Dungeon (Book 1) is a structured dungeon crawler. There is a lot of bookkeeping but almost no journaling. It closely resembles a video game as it's very mechanical. The game is devoid of spark tables.

Whats in the next room? Roll d100. Which part on my body receives damage? d10. What kind of lock door is this? d100. What is the next quest? d100.

I recommend d100 dungeon for those overwhelmed by the openness of Mythic Game Emulator or Ironsworn. The dice do a lot of heavy work.

There's two big flaws with d100 Dungeon. The rules are spread out over multiple books once you expand the game. Quick level up is found in Book 2. Destroying doors is in Book 3. Combat Experience is found in Book 4. Overland adventures are found in Book 6. It goes on. Due to the above, the game can get pricey once you start adding books.
