Yeah. DCC holds an appeal for me specifically because you get to roll D7s, D16s, D24s, etc.
...yep, ever if our fantasy campaigns were to stray from fifth-edition lingua-franca, DCC's zocchi dice tug at my deviant heartstrings something fierce...
Why can't you switch away from 5e? DCC's rules are quite simple and there's a free Quick-Start
...oh sure, we could switch at anytime but part of the beauty of everyone playing the same system is full interoperability across pick-up campaigns regardless of source material, DM, or player...you can kind of pretend like everything takes place in a shared multiverse without it, but it becomes more of a tacked-on narrative conceit (with a lot of mechanical finesse to support) rather than an emergent property of shared system mechanics...
