@mianngu This is true. But at the same time, reading new rule systems can be really inspiring and can trigger unexpected ideas. The offer some new possibilities for how to play that aren't apparent when you only know one system. Plus, it can be just kind of refreshing. Although my team plays 90% D&D, our 3 sessions of Shadow of the Demon Lord have been a fun change of pace. SotDL is D&D adjacent so it's not a huge leap, but I'm also learning Champions 6th Edition (Hero System 6e) and it's soooo different from D&D or Pathfinder, it's like another world. There's fun in just learning a new rule system.
