Hey @Kurt_Frary, it’s absolutely fine to mess around with the gravity scale and is quite common if you want to uniformly affect everything in the scene.
-9.81 may be the “realistic” value but games will often break with reality to make the experience feel better.
If you don’t want to affect everything in the scene in the same way then you could also opt to apply specific gravity rules to different objects under certain conditions. For instance, you may want to mess with the gravity of your player during a jump to give them a nicer feeling of “hang time”.
There’s really no “right” way to do things and you can play around with how your world works as much as you like. The only important thing is that you deliver the player experience you want.
