I like that we get some customization. You can really personalize your trainer so it feels like your own journey, and not just a wrote script you're following, as someone else.
The character designs themselves look really plain. I could hazard that there are at least a few items in the game you can collect to dress yourself up. I hope that is the case. It would make sense that the outfit is so plain, then. Overall though, I do like that the clothing style seems to have it's own flavor, different from the other player characters thus far.
