Just to add a level of challenge, I started the game off by inserting an OC trainer of mine into the game- someone who has rules built in to provide a challenge. It certainly has made the game hard in some aspects, but just like each gym, I adapt and overcome what lies ahead.
I will not go into more details unless you want to know more. Don't want to potentially distract from introductions.
Anyways, I have played pokemon ever since it first came out in red and blue- dedicated of it enough as I kid to where I got an honest to hearts event mew from back in the Gameboy era
