To Create or Adapt

The material in this section can be used as an example for when you actually need to make your own rules elements or adventure and for when you can adapt. Many times, a small adjustment to an existing creature, item, adventure, or other part of the game can serve you just as well as building something brand new. For example, you might add a ranged attack to a classic Pathfinder creature or create a variant version of a creature from Alien Core. Before you delve into creating your own new content, ask yourself a few questions.

1. Does something similar already exist? Look beyond the surface level. Maybe you want a small, low-level robot that's sneaky. It might not look like a squox on the surface, but copying the statistics for the squox are going to get you mostly there.
2. What do you need to change between your idea and the existing material? This will help you decide between using the original rule with minimal modification, using the original with adjustments, starting with the original as a framework to build your own, or just starting from scratch. Typically, creating something from scratch is a lot more work than modifying existing content.
3. How much time do you have to prepare the content? If time is tight, you might want to spend your time on something with a bigger impact. The less important an element is to your game, or the less time you'll be using it at the table, the more likely you should modify something that already exists. Unless you're building your entire game world from scratch, you can usually wait to implement any new rules and creations until you think you'll need it for your next session.
