>>33356915A fresh experience would be ideal, don't reuse old characters because the audience would hold you to even more expectations once recognized, and you'd have more creative control.
>1st person or 3rd person narrative?I prefer 3rd person narrative so you aren't stuck following the adventurer, and can explain some things better.
>What Pokémon should be featured?Ideally, you should aim to give a nod to the original 151 Pokemon if you want a sense of wholeness, but most can be very indirect, where the only ones fleshed out as encounters or companions or enemies can be a mix of instantly recognizable Pokemon and Pokemon much less frequently given the spotlight, to appeal to both those at a distance to the franchise and to those well-versed in it. For example, the starters are a must as is Pikachu, but Nidoking, Dewgong, Venomoth, and Poliwrath would make for exotic and diverse choices.
>Who should I write for the protagonist?Create your own character with a goal, like the person doesn't have to be on a quest to become a Pokemon master, more like out to solve a mystery or take revenge but needs to make a journey to someplace and assemble a team -- it could be very Journey to the West. Considering it's for your daughter, a female role model would be a nice touch.
>Is there any other media beyond the Red & Blue Versions that I should research? Is the anime worth researching?If you look into the anime, it's strictly for behavior and understanding how certain Pokemon move or interact. Don't take cues like them saying their name for speech -- the game should take precedence over that with its noises for them. Try Bulbapedia, since it's pretty extensive with descriptions of each Pokemon and can cover lore where the game is seeming vague to you.
>Should I take any creative liberties to make this Pokémon world feel more unique?Have more engrossing motifs, like for example an integration of Pokemon with police, construction, security, etc.
