Amateurs. Tears make regular appearances around my table. In one campaign, I broke every player's heart, slowly, between dreams and events, dying gods, and intense inner conflict- I had a cleric choose the party's NPC (The paladin)over her god AFTER he killed her(I had every player choked up that session), and I had more than half the party weep (in and out of character) upon defeating the villain responsible for all the woes of the campaign.
That was not unique for my campaign world. In another campaign, the party's most trusted ally (the same NPC from the previously mentioned campaign)sends them to defeat an enemy group bent on "liberating" their continent from humans who took it from them in a horrible genocidal war 60 years earlier. Of course, the party can't entirely disagree with their tragic villains, even falling in love with them. After a series of super emotional battles, taking down their enemies one by one, the party learns their dear friend was the employer of said villains. Conflicted and angry, the party must kill him or be killed by him. Walking out of the final battle, the party's rogue stops, and tearful, asks "We won, right?"
And then, we have our horrible genocidal war. The Sundering swept the continent in a fairly short period of time. of 267 clans of elves, 41 survive. Nearly everything in the world the group spent more than 10 years(campaign after campaign) getting attached to is taken from them brutally. Their homes destroyed, NPCs they thought would be there always were slain in fashions everyone thought impossible, all their hard work destroyed by their neighbors. The entire campaign is heartbreak after heartbreak, and it starts with the sudden and inglorious murder of Elminster, who is slain and put on display because he covered the retreat of Khelben Arunsun and Laerel from Waterdeep.
After their escape (and not all of them escaped), they had the opportunity to see what was left. 10,000 years of history reduced to ash, and now they are to rebuild in a new land. After the Sundering was completed, my players of more than 10 years, tears in their eyes, turned to me and said "You bitch. That was beautiful... and heartbreaking, and we couldn't look away. You bitch." They took me out to dinner at a 5 star restaurant, got me drunk, and reminisced for hours.
At the end of the night, I grinned to all of the. "Hey guys, guess what." after a lengthy pause they responded. "what?"
"I'm not done yet."
