It’s a wide world of games out there, and it’s nearly impossible to truly experience the richness of the RPG hobby if you only play one. Even if your group is set in their ways, or deep into a multi-year campaign, you can still take a look across the hobby and see what new ideas are cropping up (and have been cropping up for the last four decades). Reading some games can seem daunting, and certain incumbents in the industry benefit by making the whole process of reading in the hobby seem more difficult than it actually is (you know, the incumbents that make you buy three books to run their game). That said, role-playing games are not as difficult as some would make it seem, and 400 page books need not scare you away.
