The Green Hermit
Hero
Not a fan of wandering monsters, if they're just meant to be mostly combat. A list of a mix of interesting encounters is much more likely to grab my interest. I remember an old Paizo module that had the best random encounters I'd ever seen, from an ogre searching for his lost wedding ring to weird hexy things hanging from trees. Added a lot of flavour, without just being, a collection of critters looking to make a meal out of the player characters.
I like a mix of combat encounters and non-combat encounters. The latter is more difficult as it takes some thought, although probably more rewarding than just rolling initiative and killing something. But overall I do think random encounters make the world seem more alive. I've adopted something one of my players started talking about one day: "Let's hope the DM doesn't roll a 20 on the random encounter!" Now of course there is no such thing in the rules as a "critical random encounter" but since then I've been doing exactly that, making a natural 20 a more dangerous or adversarial result than it would normally be.
I also like a mix. Of course, my dice always seem to roll up the number I am least excited about. I might steal that d20 rule.
That is why I miss the initial encounter reaction rules we had in the 1ed. Not every encounter had to be a combat. Sometimes, especially in the case of NPC groups, it could led to an alliance, simple friendship, an uneasy truce, a friendly competition as to whom will get to the final vilain first to even a rescue of said group a bit further in the adventure.
I had over the years many recurring NPCs that were originally only random encounters in a dungeons (or more often, in the underdark).
Do you remember what they were? 5e is the only edition I have played, although I have used previous editions for source material.
