This post was partially sparked by a discussion in the OSR discord, which was mostly just me and some others joking around, but I do have some of my own thoughts on the matter.
But before we get into that, let's show some of the thoughts people had:
- the radius of the system's fireball spell.
- the optimal size of a dungeon room is big enough that it's a shock when it is packed wall to wall with goblins but small enough that that number of goblins doesn't threaten the verisimilitude of the local ecosystems.
- The optimal size for a dungeon room is three times as large as is physically possible from the outside.
All great points to be sure.
