Awesome RPG! I originally thought DCC was merely a retro-clone of original D&D, but after reading the core book I learned that DCC is the best realization of the 1E AD&D Appendix N in RPG form. I currently play and run a campaign in 5E, but I'm trying to get my players to at least try a one-shot of DCC. The things I love about DCC: the artwork is the best, bar-none for any fantasy RPG book; the writing is concise, easy to understand, and engaging (as much as I love 5E there have been sections of the core books that put me to sleep); magic is mysterious, somewhat uncertain, and potentially corrupting; the 0-level funnel looks very fun and filled with action; player characters have humble beginnings and are unlikely to be superpowered in ability scores; character classes are simple; luck as an ability score adds an interesting element to rolls; the critical fumble and critical success tables are fun; the dice chain is an interesting mechanic; and finally, player characters are vulnerable (in 5E it's really hard for a player character to die).
