I’ve started running Curse of Strahd and have been having a ton of fun making wacky homebrew things for my party and tweaking the module. Unbeknownst to the players so far, I have made them all a secret Dark Power trying to use them to usurp Strahd and Vampyr, and they’re just waiting to offer their dark gift.
For example, I have a druid with some fire giant ancestry who loves Produce Flame and is their front line, so he’ll be offered a slightly weaker Rage with the Path of the Storm Herald desert feature to use once per long rest. The celestial warlock would get charges to boost his Eldritch Blast damage and some secondary healing in exchange for sapping his life.
Giving my players powerful upgrades alongside typical class advancement can make some encounters harder to balance around, but as long as we’re all having fun who cares about balance??
As a DM, my favourite part is the worldbuilding. I love figuring out how the setting works, what its history is and who the prominent people are. I do worldbuilding as a solitary activity sometimes, but having an audience makes it better and having a participatory audience is best. I ran a year-long campaign I called the “zero-prep campaign” where I didn’t do much or any preparation ahead of each session, letting the party’s decisions guide things and frantically filling in the universe around them as they went, and I managed to produce one of my most cohesive and fun settings yet.
As a player, it’s similar but much smaller scale - I focus on building my character. I try to settle in to his or her skin, get to know them, figure out what they think about and how they’d react to various situations. The character is on a road I don’t know the ultimate destination for and I am keen to find out.
I like the term “zero-prep campaign”. I think I want to use that now. I’ve also had the most fun with those, although planning ahead can be very rewarding in its own right.
