Theory of Games
Storied Gamist
You need flawed PCs who bring about their own downfall. Better to use GURPS or another ttrpg that gets into the personality traits of the PCs and their flaws can be exploited by the GM. Actually, no other ttrpg would do this better than GURPS since its Disadvantages are perfect for creating flawed characters.So, let's talk genre in D&D.
One of the harder genres to splice into the heroic fantasy of standard D&D is tragedy. To evoke the pathos of someone doing their best to do good and utterly, completely failing.
How do you evoke this? What in D&D seems to get the most in the way of it? Can you cause the players to feel pathos like that in your games? Do you ever inflict tragedy...on the PC's? Or is it NPC-only? How can the players see a tragedy about to play out and NOT intervene to fix it?
For the sake of this discussion, assume that there was a good session zero and everyone's on board with a bit of a gut-punch, but also that fundamentally PC's are assumed to survive (assume basically a 1-15-or-so game where the party remains consistent).
D&D lacks the depth.
