Beyond that NPC, the routes around a town with a gym almost always have Pokemon you can catch that are effective at fighting the gym. You know, because Pokemon is very well designed game that encourages its main themes.
Speaking of game design, let's talk about music in a game. When I watched the stream Brianna did awhile back, one of the things that stuck out to me among all the other blunders was how badly the music for Rev60 is handled. Whatever is playing at any time doesn't feel "right" for the scene it's in and it doesn't do anything to enhance the mood. Final Fantasy battle music is frantic to get you pumped for the fight or, to use a Pokemon example, the Lavender Town theme is eerie and haunting due to the graveyard there. What am I supposed to feel when that one song Wu is so proud of plays? A better use of Brianna's time would have been to scour the royalty-free music sites to find something that could have worked for the game better. Then again, that's more work than checking lighting boxes in Unreal.
