Each game has a specific style/way it’s designed to be played. The system is for that specific thing, and usually it’s worth playing through at least a quick start, starter set, or simple module to figure out what that game demands.
This doesn’t mean you shouldn’t hack or homebrew, but you should keep in mind what the system wants when you’re bolting things on to it.
I feel (rightly & legitimately) called out 😭 I literally got two months into my renaissance political intrigue campaign before I discovered Court of Blades. It's a perfect fit for my interests, but now my campaign is lousy with so many d&d tropes (Tieflings! Dhampirs! Changelings! Dragons!) that I more than likely couldn't switch systems without home brewing everything out the wazoo 😓
I ran into my friends who are going to start a new pair of D&D 5e games. They don't want to play the recommended encounters per day, and want to also use milestone leveling.
I just can't understand why they buy 5e modules, then run them against 5e design? (Yes, most wotc modules are bad, but CoS at least can be run in the right way).
They would have so much more fun with Dungeon World, or an OSR system.
